Abstract:Both commercial and scientific applications often need to transform color images into gray-scale images, e.g., to reduce the publication cost in printing color images or to help color blind people see visual cues of color images. However, conventional color to gray algorithms are not ready for practical applications because they encounter the following problems: 1) Visual cues are not well defined so it is unclear how to preserve important cues in the transformed gray-scale images; 2) some algorithms have extremely high time cost for computation; and 3) some require human-computer interactions to have a reasonable transformation. To solve or at least reduce these problems, we propose a new algorithm based on a probabilistic graphical model with the assumption that the image is defined over a Markov random field. Thus, color to gray procedure can be regarded as a labeling process to preserve the newly well-defined visual cues of a color image in the transformed gray-scale image. Visual cues are measurements that can be extracted from a color image by a perceiver. They indicate the state of some properties of the image that the perceiver is interested in perceiving. Different people may perceive different cues from the same color image and three cues are defined in this paper, namely, color spatial consistency, image structure information, and color channel perception priority. We cast color to gray as a visual cue preservation procedure based on a probabilistic graphical model and optimize the model based on an integral minimization problem. We apply the new algorithm to both natural color images and artificial pictures, and demonstrate that the proposed approach outperforms representative conventional algorithms in terms of effectiveness and efficiency. In addition, it requires no human-computer interactions. &copy; 2010 IEEE.

Abstract:Three operating modes of femtosecond and picosecond pulses, which are independent self mode-locking, cross mode-locking and multi-pulse operating, are presented in a two-beam-pumped Ti: sapphire laser. Group velocity dispersion, self-phase modulation, cross-phase modulation, gain competition and self-amplitude modulation in the femtosecond and picosecond cavities are analyzed. The results show that, in the independent self mode-locking mode, group velocity dispersion and self-phase modulation largely determine the properties of the self mode-locked pulses, and in the cross mode-locking mode, the femtosecond and picosecond pulses are highly synchronized with a timing jitter of 517 fs and wavelength tuning ranges of 36 and 22 nm in the femtosecond and picosecond cavities, respectively. In the multi-pulse mode, the femtosecond pulse is still a single pulse, while the picosecond pulse splits into three sub-pulses, which is separated in time by 426 fs.

Abstract:We experimentally investigate the soliton pairs in a passively mode-locked erbium-doped fiber laser with large normal cavity dispersion. By adjusting the polarization state, four different kinds of soliton pairs are achieved. The pulses in soliton pairs exhibit different temporal separations, and show randomly distributed spikes on the top-flat of spectra. The pulse-pulse interactions in the soliton pairs are investigated, and it is suggested that the pulse separation, pulse duration, and their relative intensities all determine the strength of pulse interactions. &copy; 2010 Elsevier B.V.

Abstract:We have experimentally observed the transitional and steady mode-locking (ML) evolution of dissipative solitons (DSs). It is found that pulses with different energies can coexist in the cavity during the evolution. When an additional pulse is generated from the laser, it initially exhibits weak intensity, and then gradually develops into the fully grown pulse with the increase of pump power. Meanwhile, the spectral profile of pulses is modulated at its top. The dynamic processes occur stage by stage, and can be regarded as the transitional states between the two nearby steady ML states. To our best knowledge, this is the first report on experimental observations for the detailed dynamic evolutions of pulse shaping in a DS laser. &copy; 2010 Optical Society of America.

Abstract:We report on experimental observations of dual-wavelength solitons in a passively mode-locked erbium-doped fiber laser. Two kinds of dual-wavelength solitons with different spectrum shapes are achieved. One is exhibited to have spectrum sidebands and the other one is shown to have the smooth profile without any sideband. The mode-locking mechanism at different central wavelengths is analyzed. Experimental results suggest that the pump level together with the cavity filtering effect play key roles in the generation of the dual-wavelength solitons. &copy; 2010 Pleiades Publishing, Ltd.

Abstract:Wave-front coding was proposed in 1995 and is a powerful system-level technique used to extend the depth of field (DOF) of incoherent imaging system. The key to wave-front coding lies in the design of suitable phase masks which make the imaging system insensitive to defocus and defocus-related aberrations. Among all phase masks used for wave-front coding, odd-symmetric types are dominant and can provide larger extended DOF. With the acceptable degradation of MTF (Modulation Transfer Function) taken as a criterion, optimization procedure is used to obtain the optimum parameters for popular odd-symmetric phase masks and then a comprehensive analysis is carried out by considering four factors: DOF extension capability, sensitiveness to elementary aberrations, PSF (Point Spread Function) shifting effect and restorability of intermediate blurred images. To the best of our knowledge, the comprehensive analysis on performance of popular odd-symmetric phase masks, as done in this manuscript, has not been made before. So, the work reported here could be considered as a complementary part to the field of wave-front coding. &copy; 2010 Copyright SPIE - The International Society for Optical Engineering.

Abstract:The principle of the radiation calibration of TDI-CCD spatial stereo camera is introduced in detail in three aspects of dark current data, relative calibration and absolute calibration. Then the process of the radiation calibration is briefly described. Finally the data measured during the calibration is disposed and analyzed. How the dark current is eliminated effectively and the method of the relative calibration in each condition is mainly illustrated. In order to effectively eliminate the dark current, a part of the direct current, two methods are compared. In the process of relative calibration, the calibration matrices are calculated after analyzing a huge number of data. And in the tolerance of the system, the most suitable matrix to any condition is optimized among many matrices. It is proved that the average deviation of any calibrated image is usually between 0.08 and 1.5 in gray value, and the maximum error is 2.80%. So the complexity of the calibrating process is decreased in the practical application, and the image processing in the later stage of the work is also simplified.

Abstract:A model describing the dissipative soliton evolution in a passively mode-locked fiber laser is proposed by using the nonlinear polarization rotation technique and the spectral filtering effect. It is numerically found that the laser alternately evolves on the stable and unstable mode-locking states as a function of the pump strength. Numerical simulations show that the passively mode-locked fiber lasers with large net normal dispersion can operate on multiple pulse behavior and hysteresis phenomena. The experimental observations confirm the theoretical predictions. The theoretical and experimental results achieved are qualitatively distinct from those observed in net-anomalous- dispersion conventional-soliton fiber lasers. &copy; 2010 The American Physical Society.

Abstract:The detection ability of high resolution photoelectric detection system, to a great extent, is limited by the stray light. Since various factors influence stray light of optical system, its stray light must be tested in order to control the final indicators, such as point source transmittance (PST). On the base of star-simulator with huge dynamic range, the stray light test facility is designed, and the problem that dynamic range of single detector cannot cover 10<sup>8</sup> is solved. Under a reasonable signal-to-noise ratio, the test range of stray light PST with electron-multiplying CCD (EMCCD) is analyzed. Through analysis, the range of the stray light PST can reach 10<sup>-2</sup>-10<sup>-8</sup>, and meet the requirement for testing high resolution photoelectric detection system's PST.

Abstract:Second-harmonic generation (SHG) through a proposed thin gold film with a periodic array of subwavelength nanoholes is numerically investigated. By using a recently developed microscopic classical theory and a fullvectorial three-dimensional finite-difference time-domain method, we demonstrate that the mirror symmetry of nanoholes in one direction restricts the polarization state of second-harmonic emission in the same direction. Numerical results show that the second-order nonlinear susceptibility x<sup>(2)</sup><inf>yyy</inf> dominates in the process of SHG when the nanoholes possess mirror symmetry in the x-axis direction. It is also found that the surface plasmon resonance can result in the enhancement of SHG from metallic nanoholes. &copy; 2010 Optical Society of America.

Abstract:This paper presents a new method for detecting small moving targets from consecutive image sequences. Image sequences are processed to detect targets, assuming that the data samples have been spatially registered. Firstly, Maximum Value Projection and normalization are utilized to reduce the data samples and reject the background clutter. Then, targets are detected using connected component analysis. At last, the velocities of the targets are estimated by centroid localization and least-square regression. A sliding neighborhood operation is performed before target detection. It can greatly reduce the computation while preserving as much target information as possible. The experimental results indicate that this method can efficiently detect the small moving targets and accurately track their traces. Both centroid locating precision and tracking accuracy are within a pixel. &copy; 2010 IEEE.

Abstract:The interferometric data acquired by Fourier transform spectrometer was a betweenness which couldn't be used directly. For the successful application of the interferometric data, spectrum recovery processing must be adopted. The conventional method based on inverse Fourier transform was frequently used for spectrum recovery. According to the principle analysis of the interferometric data, the mixing model was induced, and the spectrum recovery method based on the mixing model of the interferometric data was presented. Finally, the computer simulation for these two methods mentioned above was implemented, and the recovered spectra were compared with the standard spectrum. The simulation results indicated that the spectral precision of the new method was better than the conventional method, which provided a new scheme for spectrum recovery.

Abstract:Tin-doped indium oxide (ITO) conductive thin film is prepared on MgF<inf>2</inf> substrate by electron beam evaporation. The effect of oxygen and annealing on the sheet resistance and ultraviolet (UV) transmittance of ITO film is investigated. Furthermore, the properties of ITO film are compared with conventional conductive film substrates Au and Cr. The surface morphological image, sheet resistance, microstructure and transmittance curves in the wave band of 190~800 nm are investigated by optical microscope (OM), four-probe method, high resistance meter, X-ray diffractomer (XRD) and spectrophotometer. Variation range of transmittance is acquired in the wave band of 200~400 nm when the sheet resistance reaches 10<sup>7</sup> &Omega;. The results indicate that the sheet resistance of thin film prepared with oxygen is higher than that without oxygen; after annealing the sheet resistance of thin film decreases and the microstructure changes from amorphous to polycrystalline. Compared to Au and Cr, the average transmittance of ITO film with the same sheet resistance of 10<sup>7</sup> &Omega; or so, which is prepared with oxygen and annealing, is 10% higher in the wave band of 200~400 nm.

Abstract:Based on in-depth analysis of the relative radiation scaling theorem and acquired scaling data of pixel response nonuniformity correction of CCD (charge-coupled device) in spaceborne visible interferential imaging spectrometer, a pixel response nonuniformity correction method of CCD adapted to visible and infrared interferential imaging spectrometer system was studied out, and it availably resolved the engineering technical problem of nonuniformity correction in detector arrays for interferential imaging spectrometer system. The quantitative impact of CCD nonuniformity on interferogram correction and recovery spectrum accuracy was given simultaneously. Furthermore, an improved method with calibration and nonuniformity correction done after the instrument is successfully assembled was proposed. The method can save time and manpower. It can correct nonuniformity caused by other reasons in spectrometer system besides CCD itself's nonuniformity, can acquire recalibration data when working environment is changed, and can also more effectively improve the nonuniformity calibration accuracy of interferential imaging spectrometer system.

Abstract:We report on a long-cavity passively mode-locked fiber laser in the anomalous dispersion regime. The nonlinear polarization rotation technique is employed to achieve mode locking. The output pulse from the fiber laser has a rectangular shape and a corresponding Gaussian-shape spectral profile. Stable mode-locked pulses at a repetition rate of 278 kHz with single pulse energy as high as 715 nJ are obtained under equal bidirectional pumping power of 500 mW in cavity. The experimental results demonstrate that the passively mode-locked fiber laser operating in the anomalous regime can also realize a high-energy pulse, which is different from the conventional low-energy soliton pulse. &copy; 2010 Optical Society of America.

Abstract:A new method based on the double-beam polarization balance bridge technique for measuring the ultralow total loss, including absorption, scattering, and reflection in ultrahigh antireflection mirror is presented. By rotating the polarizer before and after the insertion of a mirror into one beam out of the Wollaston prism to adjust the intensities of the two beams to be equal, the total loss can be obtained by recording the angle variation of the polarizer. The factors affecting the measurement precision of the technique and the main sources of errors are investigated in detail. The total loss measurement precision of the mirror is 10 ppm and the zero drift is 10 ppm at 632.8 nm. &copy; 2010 American Institute of Physics.

Abstract:A series of chalcogenide glasses based on the composition Ge<inf>30</inf>Ga<inf>5</inf>Se<inf>65</inf> (at.%) doped with the different Tm<sup>3+</sup> ions were synthesized by melt-quenching technique. The refractive indexes, Raman spectra, absorption spectra, near-and mid-infrared fluorescence, and lifetimes of glass samples under 800 nm laser excitation were measured. The intensity parameters &Omega;<inf>i</inf>(i=2, 4, 6), transition probabilities, branching ratios and radiative lifetimes have been predicted for Tm<sup>3+</sup> ions in samples by using the Judd-Ofelt theory. The near-infrared emission spectra at 1.23, 1.48 and 1.8 &mu;m were observed and their quantum efficiencies were evaluated respectively in glass doped with 1 Wt% Tm<sup>3+</sup>-ions under 800 nm excitation. The mid-infrared fluorescence spectra were investigated with the different Tm<sup>3+</sup> ion concentration under 800 nm excitation. The multiphonon relaxation rate of Tm<sup>3+</sup>: <sup>3</sup>H<inf>5</inf> &rarr <sup>3</sup>F<inf>4</inf> by the measured and calculated lifetimes, and the relative parameters of W(0) and &alpha; in Ge<inf>30</inf>Ga<inf>5</inf>Se<inf>65</inf> glass were evaluated. Results show that the multiphonon relaxation rates were significantly lower than other glasses due to the lower maximum phonon energy, so the selenide glasses are promising as host materials for doping by rare earth ions and for preparation of mid-infrared optical elements.

Abstract:A novel type of photonic crystal fiber (PCF) with low dispersion and high nonlinearity for four-wave mixing is proposed. This kind of fiber is composed of a solid silica core and a cladding with squeezed-hexagonal-lattice elliptical air-hole along the fiber length. Its dispersion and nonlinearity coefficient are investigated simultaneously by using full vectorial finite element method. Numerical results show that proposed highly-nonlinear low-dispersion fiber has the total dispersion as low as &plusmn;2.5 ps/(nm&middotkm) over ultra-broad wavelength range from 1.43 &mu;m to 1.8 &mu;m by adjusting the structure parameters of photonic crystal fiber, such as the hexagonal squeezing ratio, the relative air hole size and the air hole ellipticity, and the corresponding nonlinearity coefficient is about 150 (W&middotkm)<sup>-1</sup> at 1.55 &mu;m. The proposed PCF with low ultra-flattened dispersion, high nonlinearity and high birefringence can have important applications on the four-wave mixing.

Abstract:Based on the basic theory of polarization measurement, this paper compares the differences between two detection angles: 45&deg; and 60&deg;, which are generally used in rotating polarization elements method for polarization measurement. Sequentially, an optimization detection angle is present, and it provides a better angle choice for polarization measurements which could obviously improve the polarization measurement accuracy and effectively reduce the influence of rotation errors to the degree of polarization. &copy; 2010 Copyright SPIE - The International Society for Optical Engineering.

Abstract:The mechanism and intrinsic conditions of high-energy wave-breaking-free pulse generation in fiber lasers mode-locked by a nonlinear polarization rotation technique are investigated numerically and experimentally. Both numerical and experimental results show that the pulses along the two orthogonal polarization axes of the fiber have a large difference in pulse energy. The numerical simulations show that the ratio of the energy of two components is limited and ranges from about 8 to about 65. The slope of the instantaneous frequency at the central position of the pulse decreases rapidly with the increase of the pulse duration and energy, whereas the slope at the pulse edge changes slightly. The accumulation of instantaneous frequency throughout the pulse width approaches a constant in a higher pulse energy regime. Understanding the mechanism and intrinsic conditions of the wave-breaking-free pulse generation could be useful in generating high-energy pulses delivered from fiber lasers. &copy; 2010 The American Physical Society.

Abstract:The structure of GeS<inf>2</inf>-Sb<inf>2</inf>S<inf>3</inf>-CdS pseudo-ternary system glass was investigated by using Raman spectroscopy. The results show that the basic structure units forming the glass network are quasi-three-dimensional (3D) [GeS<inf>4</inf>] tetrahedra and quasi-two-dimensional (2D) [SbS<inf>3</inf>] pyramids. With the increase of Sb<inf>2</inf>S<inf>3</inf> content, the structure of glass transfers from the 3D structure to the [GeS<inf>4</inf>]<inf>m</inf>, [SbS<inf>3</inf>]<inf>n</inf> formed layer or chain structure, which is interconnected by Ge-S-Sb bridging sulfurs and Sb-Sb, Ge-Sb, Ge-Ge metallic bonds. CdS can bring some non-bridge sulfurs and decrease the degree of polymerization. Because of the additions of Sb<inf>2</inf>S<inf>3</inf> and CdS, large amount of metallic and dangling bonds are formed; therefore, the number of defects of glass is increased.

Abstract:The influence of deflector position on characters of the streak tube is discussed. A large amount of electron trajectories are figured out by statistical simulation method, and the modulation transfer function(MTF) used to evaluate temporal and spatial resolution is calculated. The conclusions are as follows: the streak tube has obtained the optimal temporal resolution when the deflection plate is set to the aperture of anode, and the optimal spatial resolution is obtained when deflection plate is set to the point with minimum electron beam diameter. In addition, any perpendicular deviation of deflection plate from the axis of streak tube can worsen both temporal and spatial resolution worse, thus axis of the deflection plate should strictly overlap with the center axis of the streak tube.

Abstract:It is important to design an effective and efficient objective metric of the video quality in video processing areas. The most reliable way is subjective evaluation, thus the most reasonable objective metric should adequately consider characteristics of the human visual system (HVS). Visual attention (VA) is one of the essential visual phenomena of HVS, the realization of which relies on the saliency of visual field. Moreover, the saliency of visual field has a great influence on recognition, memorization and subjective evaluation of the image. This paper explores the saliency of visual field for objective quality assessment of videos. The proposed method first uses the VA model to obtain visual saliency map of the distorted video, including color, intensity and motion. Then the salient map is used to weight a structural similarity map between the original and distorted videos to get the final value of the video quality. Experimental results prove that the proposed method achieves a good correlation with subjective valuation. &copy;2010 IEEE.

Abstract:A typical infrared detection system [Ritchey-Chretien (R-C) system] and its baffles are designed. Its structure model is established with the TracePro software. Stray lights caused by thermal radiation of critical inner surface are analyzed by a ray tracing program. The relation of photons of stray lights and temperature which varies from 250 K to 320 K is given. The stray light caused by sky background is calculated. The curve of increasing rate of photon number of stray lights received by single pixel versus temperature is given. The results show that an open telescope without main tube cannot do well obviously in reducing stray lights. The temperature of the inner baffle of main mirror should be less than 230 K in order to detect the background-limited target.

Abstract:Based on the vectorial Rayleigh-Sommerfeld diffraction integrals, the analytical expression for the spectral intensity of a vectorial nonparaxial ultrashort pulsed Gaussian beam diffracted at a rectangular hard-aperture is derived. The results of the far-field and paraxial cases can be regarded as special cases of the general expression. Effect of vectorial nature on spectral anomalies of ultrashort pulsed beams passing through a hard-edged aperture is analyzed in detail. It is shown that the spectral switch near the phase singularity, which is predicated under the condition of the scalar paraxial theory, disappears with the increasing effect of the vectorial and nonparaxial nature. &copy; 2009 Springer-Verlag.

Abstract:High birefringence induced by rhombic air-hole photonic crystal fibers (PCFs) is numerically analyzed by using the finite-element method. The birefringence of a few kinds of PCFs was investigated with different parameters related to rhombic holes, including the rhombic-hole shape, size, and spacing. It was found that the birefringence of the proposed rhombic-hole PCF in this study is relatively larger than that of an elliptical-hole PCF with the same air-filling fraction (f = 0.0375) when the ratio of the rhombic-hole diagonal length is equal to the elliptical-hole ellipticity. &copy; 2010 Optical Society of America.

Abstract:Fourier transform imaging spectrometer is a new technic, and has been developed very fast in recent ten years. When it is used in satellite, because of the limit by the data transmission, the authors need to compress the original data obtained by the Fourier transform imaging spectrometer, then, the data can be transmitted, and can be incepted on the earth and decompressed. Then the authors can do data process to get spectrum data which can be used by user. Data compression technic used in Fourier transform imaging spectrometer is a new technic, and few papers introduce it at home and abroad. In this paper the authors will give a data compression method, which has been used in EDIS, and achieved a good result.

Abstract:The electronic structure and magnetic properties of Fe-doped SiC nanotubes are investigated by using the first-principles method based on density functional theory (DFT) in the local spin density approximation (LSDA). The calculation results indicate that the SiC nanotube of Fe substitution for C exhibits antiferromagnetism while ferromagnetism features prominently when Fe substitutes Si. This is a kind of half-metal magnetic material. The formation energy calculation results show that the formation energy of ferromagnetic structure is 3.2 eV lower than that of antiferromagnetic structure. Fe atoms are more likely to replace Si atoms. Spin-orbit coupling induces electron spin polarization in the ground state. Also, the doping Fe atoms make relaxation towards the outside of the tube to some extent and larger geometric distortion occurs when Fe substitutes C, but the whole geometric structure of SiC nanotubes is not damaged due to the doping. It is revealed in the calculation of energy band structure and density of states that more dispersed distribution of energy levels is produced near the Fermi level. For Fe substitution for Si, obviously there are spin-split and intense p-d hybrid effects by Si 3p electron spins and Fe 3d electron spins localized at the exchanging interactions between magnetic transitional metal (TM) impurities. Spin electronic density results indicate that system magnetic moments are mainly generated by the unpaired 3d electrons of Fe atoms. All these results show that the transition metal doping SiC nanotube could be a potential route to fabricating the promising magnetic materials. &copy; 2010 Science China Press and Springer-Verlag Berlin Heidelberg.

Abstract:Active appearance model (AAM) is a powerful generative method for modeling deformable objects. The model decouples the shape and the texture variations of objects, which is followed by an efficient gradient-based model fitting method. Due to the flexible and simple framework, AAM has been widely applied in the fields of computer vision. However, difficulties are met when it is applied to various practical issues, which lead to a lot of prominent improvements to the model. Nevertheless, these difficulties and improvements have not been studied systematically. This motivates us to review the recent advances of AAM. This paper focuses on the improvements in the literature in turns of the problems suffered by AAM in practical applications. Therefore, these algorithms are summarized from three aspects, i.e., efficiency, discrimination, and robustness. Additionally, some applications and implementations of AAM are also enumerated. The main purpose of this paper is to serve as a guide for further research. &copy; 2009 IEEE.

Abstract:Conventionally, biometrics resources, such as face, gait silhouette, footprint, and pressure, have been utilized in gender recognition systems. However, the acquisition and processing time of these biometrics data makes the analysis difficult. This letter demonstrates for the first time how effective the footwear appearance is for gender recognition as a biometrics resource. A footwear database is also established with reprehensive shoes (footwears). Preliminary experimental results suggest that footwear appearance is a promising resource for gender recognition. Moreover, it also has the potential to be used jointly with other developed biometrics resources to boost performance. &copy; 2010 IEEE.

Abstract:The vacuum-gap discharge damage of micro-channel plate(MCP) imagers based on two screen-electrode structures, with Al-screen and indium-tin-oxide(ITO) screen respectively, is investigated after first arcing. The results show that the erosion pattern of Al-screen MCP imager appears as crater, and the electric insulating strength is less than 3 kV/mm under 10 &mu;s-wide screen voltage, independent of MCP. The erosion of ITO-screen mostly appears as phosphor transporting to MCP, which drives field emission to steady state, and the electric insulating strength can reach 9 kV/mm at 10 &mu;s-wide voltage. Thus, the discharge of MCP imagers depends mostly on screen-electrode structure, and ITO-screen MCP imagers can obtain higher electric insulating strength.

Abstract:This paper presents a theoretical study of wavelength dependence four-wave-mixing (FWM) spectroscopy in a micrometric thin atomic vapour. It compares three cases termed as mismatched case I, matched case and mismatched case II for the probe wavelength less, equal and greater than the pump wavelength respectively. It finds that Dickenarrowing can overcome width broadening induced by Doppler effects and polarisation interference of thermal atoms, and high resolution FWM spectra can be achieved both in matched and mismatched wavelength for many cases. It also finds that the magnitude of the FWM signal can be dramatically modified to be suppressed or to be enhanced in comparison with that of matched wavelength in mismatched case I or II. The width narrowing and the magnitude suppression or enhancement can be demonstrated by considering enhanced contribution of slow atoms induced by atom-wall collision and transient effect of atom-light interaction in a micrometric thin vapour. &copy; 2010 Chinese Physical Society and IOP Publishing Ltd.

Abstract:Liquid lens is a novel optical device which can implement active zooming. With liquid lens, zoom camera can be designed with more miniature size and simpler structure than before. It is thought that the micro zoom system with liquid lens has a very wide potential applications in many fields, in which the volume and weight of the system are critically limited, such as endoscope, mobile, PDA and so on. There are mainly three types of tunable-focus liquid lens: liquid crystal lens, electrowetting effect based liquid lens and liquid-filled membrane lens. Comparing with the other two kinds of liquid lens, the liquid-filled membrane lens has the advantages of simple structure, flexible aperture and high zooming efficiency. But its membrane surface will have an initial shape deformation caused by the gravity when the aperture of the lens is at large size, which will lead to the wave front aberration and the imaging quality impairing. In this paper, the initial deformation of the lens caused by the gravity was simulated based on the theory of Elastic Mechanics, which was calculated by the Finite Element Analysis method. The relationship between the diameter of the lens and the wave front aberration caused by the gravity was studied. And the Optical path difference produced by different liquid density was also analyzed. &copy; 2010 Copyright SPIE - The International Society for Optical Engineering.

Abstract:Y waveguide is a key component of digital closed-loop fiber optic gyroscope, and the stability of its half-wave voltage directly affects the scale factor stability of FOG. Working temperature is the main factor that influences on the stability of Y waveguide half-wave voltage. Theoretical deduction of Y waveguide physical properties and ex-periment of half-wave voltage changing along with temperature indicate that the relationship between half-wave voltage and temperature is nearly linear. The non-linear errors are induced by Y waveguide electric field and mechanical stress. Through calibrating the Y waveguide half-wave voltage and making compensation, the optimal modulation state of FOG can be achieved and highly stable FOG scale factor can be obtained.

Abstract:Mammographic mass detection is an important task for the early diagnosis of breast cancer. However, it is difficult to distinguish masses from normal regions because of their abundant morphological characteristics and ambiguous margins. To improve the mass detection performance, it is essential to effectively preprocess mammogram to preserve both the intensity distribution and morphological characteristics of regions. In this paper, morphological component analysis is first introduced to decompose a mammogram into a piecewise-smooth component and a texture component. The former is utilized in our detection scheme as it effectively suppresses both structural noises and effects of blood vessels. Then, we propose two novel concentric layer criteria to detect different types of suspicious regions in a mammogram. The combination is evaluated based on the Digital Database for Screening Mammography, where 100 malignant cases and 50 benign cases are utilized. The sensitivity of the proposed scheme is 99% in malignant, 88% in benign, and 95.3% in all types of cases. The results show that the proposed detection scheme achieves satisfactory detection performance and preferable compromises between sensitivity and false positive rates. &copy; 2009 IEEE.

Abstract:A broadly tunable dual-wavelength erbium-doped ring fiber laser based on a high-birefringence fiber loop mirror (HiBi-FLM) and a polarization controller is demonstrated experimentally. The measured transmission spectrum of HiBi-FLM covers a wide range from 1525 to 1575 nm. The wavelength of proposed laser can be flexibly tunable during this range of &sim;50 nm by adjusting the polarization controller. In addition, the spacing of two wavelengths is adjustable by changing the length of HiBi fiber. The dual-wavelength lasers with the HiBi fiber length of 1 and 2 m are experimentally demonstrated and compared. The experimental results show that the proposed laser can stably operate on two wavelengths simultaneously at room temperature, and the output peak power variation is about 0.5 dB during 40 min. &copy; 2010 Pleiades Publishing, Ltd.

Abstract:In this Letter, we report a carbon dioxide gas sensor having 547 pieces of thin-film modified capillaries, which are derived from a microstructured polymer optical fiber preform. Compared with the conventional absorption-based sensor, the monolithic polymer capillary waveguide arrays have better sensitivity, because the huge sensing surfaces, composed of 547 pieces of dye-indicator-doped porous ethyl cellulose layers, interact directly with the gas molecules. As far as we know, a gas sensor based on multichannel capillary waveguide arrays has not been reported before. &copy; 2010 Optical Society of America.

Abstract:The paper proposed a new image matching method combining affine-invariant SIFT feature descriptor with global context. Affine-SIFT (ASIFT) can find large numbers of correct matches even with great variation of camera axis orientation, however when there are several similar regions or objects between the query and search images, it may also produce many mismatches. Therefore, we intend to introduce global context to resolve ambiguities that can occur locally when an image has multiple similar regions. A global context vector that adds curvilinear shape information from a much larger neighborhood, thus reducing mismatches when multiple local descriptors are similar. We have tested our method on various images and compare matching accuracy between the ASIFT descriptor with global context to that without. &copy;2010 IEEE.

Abstract:The collimating effect of self-generated magnetic fields on fast-electron transport in solid aluminium targets irradiated by ultra-intense, picosecond laser pulses is investigated in this study. As the target thickness is varied in the range of 25 &mu;m to 1.4 mm, the maximum energies of protons accelerated from the rear surface are measured to infer changes in the fast-electron density and therefore the divergence of the fast-electron beam transported through the target. Purely ballistic spreading of the fast-electrons would result in a much faster decrease in the maximum proton energy with increasing target thickness than that measured. This implies that some degree of 'global' magnetic pinching of the fast-electrons occurs, particularly for thick (&gt;400 &mu;m) targets. Numerical simulations of electron transport are in good agreement with the experimental data and show that the pinching effect of the magnetic field in thin targets is significantly reduced due to disruption of the field growth by refluxing fast-electrons. &copy; IOP Publishing Ltd and Deutsche Physikalische Gesellschaft.

Abstract:The bond stress is analyzed when the optics were attached to their mounts with high strength adhesive in space camera. The model was founded that a circular planar reflector supported by one, three, six or twelve adhesive points, which evenly distributed on different circles. The surface deformation of reflector is mainly caused by the shrinkage after solidity. The functional relation was deduced between the bonding force of the reflector and the characteristic dimension of the adhesive spot using piecewise function, and then analyzing the RMS error of no gravity assuming that the adhesive spot is fixed connect to the reflector using Nastran. The analytical RMS error was the aberration which added by solidification of adhesive. The calculation result is in good agreement with the experiment results. This analyzing method will be useful for the microstress clamping of high performance reflector system for application in space optical systems. &copy; 2010 Copyright SPIE - The International Society for Optical Engineering.

Abstract:This paper presents a novel and robust method for accurately extracting axis equation from axis symmetry objects. Our method combines Hough transform with centroid analysis technique to output sub-pixel axis equation. It is robust even in imperfect image qualities for fully use of regional grayscale pixel values while not relying on edges of objects. The whole process requires no information other than the input grayscale images. The results illustrate that our method is capable of extracting accurate axis while achieving near real-time performance. &copy;2010 IEEE.

Abstract:Based on the vector angular spectrum method and the stationary phase method and the fact that a circular aperture function can be expanded into a finite sum of complex Gaussian functions, the analytical vectorial structure of a four-petal Gaussian beam (FPGB) diffracted by a circular aperture is derived in the far field. The energy flux distributions and the diffraction effect introduced by the aperture are studied and illustrated graphically. Moreover, the influence of the f-parameter and the truncation parameter on the non-paraxiality is demonstrated in detail. In addition, the approximate formulas obtained in this paper can degenerate into un-apertured case when the truncation parameter tends to infinity. This work is beneficial to strengthen the understanding of vectorial properties of the FPGB diffracted by a circular aperture. &copy; 2010 Elsevier B.V. All rights reserved.

Abstract:Photo-thermal-refractive(PTR) glass is fabricated by high temperature melt process. PTR glass, a kind of sodium- zinc-aluminum-silicate glass doped with silver, cerium and fluorine, possesses both photosensitive and heat-sensitive characters. In the study, PTR glass was firstly exposed by ultraviolet light, and then after the heat treatment of the sample, the measurement of ultraviolet-visible-near infrared transmissivity spectrum and the X-ray diffraction of exposure part was performed. According to the results, the working window of PTR glass is between 400 nm and 2800 nm. The best exposure wavelength of PTR glass is 305 nm. The micro-crystallization of PTR glass can be controlled by exposure dose and conditions of two stepped heat treatment. During the treatment processes mentioned above, NaF crystal was precipitated. Because crystal particles are very tiny, visible light is not scattered in the glass.

Abstract:An actively mode-locked fiber ring laser based on cross-gain modulation (XGM) in a semiconductor optical amplifier (SOA) is demonstrated to operate stably with a simple configuration. By forward injecting an easily-generated external pulse train, the mode-locked fiber laser can generate an optical-pulse sequence with pulsewidth about 6 ps and average output power about 7.9 mW. The output pulses show an ultra-low RMS jitter about 70.7 fs measured by a RF spectrum analyzer. The use of the proposed forward-injection configuration can realize the repetition-rate tunability from 1 to 15 GHz for the generated optical-pulse sequences. By employing a wavelength-tunable optical band-pass filter in the laser cavity, the operation wavelength of the designed SOA-based actively mode-locked fiber laser can be tuned continuously in a wide span between 1528 and 1565 nm. The parameters of external-injection optical pulses are studied experimentally to optimize the mode-locked fiber laser. &copy; 2009 Elsevier B.V.

Abstract:In this paper, an adaptive blind image restoration algorithm is proposed. According to the feature that the certain blur may lead to the specific component distortion in the cepstral domain, we develop an automatic algorithm using Fourier-Mellin transform to classify and identify the point spread function (PSF) with cepstrum: for the usual types of blur, such as linear motion blur and defocus blur, we restore it with Wiener filter; while for others, we propose an improved total variation (TV) blind restoration algorithm. The algorithm combines the typical methods and blind methods of image restoration, achieving the adaptive blind image restoration. Experimental results show that it is effective in restoring degraded images under different environments, and it improves the restoring performance significantly under the presence of high noise level. &copy;2010 IEEE.

Abstract:A novel centroid algorithm is proposed to acquire better centroid performance in a star image. Since photons incident on pixels of stars present a Gaussian point spread function (PSF), so, the centroid locations on the x and y-axis are calculated using the pixel intensity ratio and expand the Gaussian PSF to polynomials with respect to the centroid location. The angular separation error between star pairs is used to verify the proposed algorithm indirectly. The result clearly shows that the centroid accuracy achieves 1/33 of a pixel and is about two times better than the moment method, indicating the new algorithm is effective. &copy; 2011 The Japan Society for Aeronautical and Space Sciences.

Abstract:Optical emission spectra of the plasma generated by a 532 nm Nd:YAG laser irradiation onto a standard aluminum alloy (E414d) was recorded and analyzed. The electron temperature was determined using the Boltzmann plot method with three aluminum spectral lines at 236.71 nm, 257.509 nm and 308.215 nm, whereas the electron density was inferred by measuring the Stark broadening line profile of Al(II) 281.619 nm. The experimental results confirmed that the local thermodynamic equilibrium was valid and the plasma was optically thin. The spectral line intensity increased initially with the increase in laser irradiance and saturated at higher irradiance levels. Results showed that the energy losses due to the reflection of laser beam from the plasma itself were insignificant. The absorption in the plasma through inverse bremsstrahlung and two-photon ionization were studied. At the same time, the variation of transition probability ratio of Al(I) 309.28 nm to Al(I) 308.21 nm with laser power density was also studied.

Abstract:Ultracompact wave plate (UWP) will be one of the key elements in future all-optical photonic integrated circuits (PICs). In this paper, we propose UWPs based on periodic dielectric waveguides (PDWs) with air holes in conventional dielectric waveguides. The mode characteristics (for both TE and TM) and birefringence of PDWs are calculated by plane wave method (PWM). The transmission efficiencies and phase changing of TE and TM waves in PDW are obtained by finite-difference time-domain (FDTD) scheme. Based on the PDWs, the quarter-wave plates (QWPs) and half-wave plates (HWPs) are designed. Calculating results show that the proposed PDW has large birefringence (&Delta;n&gt;1) and can introduce 2&pi; phase difference with a short length being less than &lambda;. The size of low order UWPs are compact. The transmission efficiency of PDW is improved by taper structure. Based on the taper PDW, ultra-wide band (&gt;100 nm) achromatic QWP is designed. Profiting from the waveguide guiding, the UWPs have low beam divergence and can be easily integrated with other photonic components. The UWPs have many potential applications in future PIC systems such as optical communications, optical measurements and sensors. &copy; 2010 Copyright SPIE - The International Society for Optical Engineering.

The experiments showed that the period of interference patterns becomes larger with increasing tilt angles of the substrate, as is in good agreement with theoretical analysis. It was also shown that there is no evident change when the rotational angle was less than 3<sup>0</sup> in our experiment. The significance of our analytical results for MLIL and the fabrication of integrated circuit was discussed. &copy;2010 IEEE.

Abstract:A novel moving corner-cube mirror interferometer (MCCMI) is presented. It has neither tilt nor shearing problems. It consists of one moving corner-cube mirror (MCCM), one fixed double-sided mirror (FDSM), one fixed plane mirror, and one beam splitter. The FDSM is a plane-parallel glass plate with both faces coated with high-reflectivity films. The effect of a FDSM tilt is analyzed. The optical path difference (OPD) is created by the straight reciprocating motion of the MCCM, and the OPD value is four times the displacement of the MCCM. The reflection characteristic of the corner-cube mirror (CCM) is analyzed by means of the vector expression, and the formulas of deviation angle of a CCM are derived. The effect of a MCCM deviation angle is analyzed. The new MCCMI is very suitable for high-resolution Fourier-transform infrared spectrometers used for atmospheric sounding. &copy; 2010 Optical Society of America.

Abstract:Multispectral image compression which are based on the one-, two- and three-dimensional wavelet transforms has been existed in many papers. Existing image compression algorithms have proved to be very efficient in compressing these kinds of images. We adopted the principal component analysis , clustering and spectral angle cosine to classify and compress in spectral dimension. In this article, we present lossy compression based wavelet; the information loss is measured by Peak-Signal-to-Noise Ratio (PSNR). We introduce the spatial compression based on JPEG2000 and improved embedded zerotree (EZW) encoding. We use the different compression rate to compress image, when the compression rate is 10:1, subjective value and object value is optimal. Not only the single band, but also the composing image, the spectral curve is nearly same. &copy;2010 IEEE.

Abstract:A effective approach to global motion compensation and moving object extraction is proposed. Firstly, feature-block detection and search-matching algorithm are used to attain background motion vectors of global image. Then, once the global motion vectors are robustly estimated, relatively stationary background can be almost completely eliminated through the registration difference algorithm. Finally, higher-order statistics is used to attain the motion target exactly. The experimental results validate that the proposed algorithm improves the performance of detection moving targets and effectively restrains the noise disturbance. &copy; 2010 IEEE.

Abstract:Controlling the stability of image invariants at every stage is proposed for extracting and selecting combined invariants. First, four stages on aircraft image recognition is discussed. Second, the benefits and shortages of four kinds of invariants, which include Hu's moments, Affine moments, Normalized Moment of Inertia and Normalized Fourier Descriptors, are analyzed. Third, multiple images for different aircraft types under various small space angles are collected and the above four invariants from these images are extracted. Fourth, the invariants are combined based on these four kinds of invariants and are optimized a new combined-invariants, which are sent to support vector machine classifier for identifying aircraft types. At last, the experiment results are shown that the recognition rate will be improved more apparently by using the optimized combined-invariants than by using the direct combined-invariants or single kind of invariants.

Abstract:By means of electromagnetic forces (Lorentz force), the structure of the flow boundary layer may be modified, which is one of the active methods for flow controlling. With the forces generated by electromagnetic fields and localized around the electrolyte liquid boundary layers, the structure of the flow boundary layer may be modified and the flow separation from the surface may be controlled effectively. The electromagnetic force provides with the effective affects of increasing the lift forces of the hydrofoil and reducing drag and controlling the hydrofoil stall. This paper is concerned about the basic theory of weakly conducting fluid boundary layer control by electromagnetic body forces, and the hydrofoil covered with electromagnetic actuators was put into electrolyte liquid. The experimental control system based on DSP chip TMS320F2812 was used to change expediently the angle of attack and speed, and measure the lift and drag of the hydrofoil. The experimental results show that positive electromagnetic force can restrain and stave off hydrofoil stall availably.

Abstract:We demonstrate the possibility of creating multiple spherical spots in a 4-&pi;- focusing system with a radially polarized beam. Using spherical waves to expand the plane wave factor in the Richards-Wolf integral, it is found that a proper spatial modulation in the amplitude of the input field with radial polarization can form multiple spherical spots with a focusing system satisfying the Herschel condition. These spots are distributed symmetrically about the focus on the optical axis with variable positions and intensities. Although we consider only the case of three spherical spots in this paper, generalization to the multiple-spots case will present no difficulty. &copy; 2010 Optical Society of America.

Abstract:An effective hybrid genetic algorithm (GA) for optimizing air-silica nanowires, the incident pulse, and supercontinuum (SC) generation, is proposed in this paper. Based on the proposed algorithm, the dispersion and nonlinearity of air-silica nanowires, as well as the duration and chirp of incident pulses, are optimized to achieve SC generation with a broader, smoother, and more intense spectrum. It is found that the optimized spectrum becomes smoother from 740 to 1500 nm and is broadened by 300 nm. Meanwhile, the spectral intensity in the range of 450-945 nm is significantly increased by a factor of 10. &copy; 2010 Optical Society of America.

Abstract:By using the hydrodynamic method, maximal transverse trapping forces on three kinds of micro-particles with radii ranging from 0.5 &mu;m to 22 &mu;m were measured by dragging these transparent dielectric beads suspended in water with the focused laser beam. The magnitude of trapping forces obtained from the experiment was of the order of pico-Newton. For PMMA particles of large size, the offset &Delta;x of the particle from the optical trapping center was measured with different dragging velocities, and the trap stiffness was calculated according to the experimental result. In addition, at the edge of optical trap, where &Delta;x is larger than the radius of the micro-particle, the optical trapping force was also measured to obtain the domain of trapping force and the relationship between the force and &Delta;x. Comparison of measured trapping forces and stiffness on yeast cells with different radii under the same condition shows that the critical velocity decreases, the maximal trapping force rises and the stiffness reduces with increase of the radius of the yeast cell.

Abstract:A scheme based on a W-shaped axicon mirror device for total-internal- reflection fluorescence microscopy (TIRFM) is presented. This approach combines the advantages of higher efficiency compared with traditional TIRFM, adjustable illumination area, and simple switching between wide-field and TIRF imaging modes. TIRF images obtained with this approach are free of shadow artifacts and of interference fringes.

Abstract:A dielectric barrier discharge (DBD) device operated at ambient air with an ac power supply was designed and examined. The discharge power and active current of DBD were characterized. Experimental results show that the discharge power does not proportionally increase all along with voltage. Through in-depth analysis of typical waveforms of instantaneous applied voltage and discharge current, and images of microdischarges in the gas gap, it is inferred that considerable reduction in charges transferred through discharge channels is most likely due to recombination and attachment to electronegative molecules, nonuniform highly distorted electric fields, and repulse of more homogeneous electric charges. &copy; 2010 American Institute of Physics.

Abstract:Tm<sup>3+</sup>-doped chalcogenide glasses in Ge-Ga-S-CsI system were prepared and the properties of glasses including density, absorption spectrum, emission spectra and fluorescence life in the near- and mid-infrared spectral region under 800 nm excitation were measured. The optical parameters such as intensity parameter &Omega;i (i=2, 4, 6), predicted spontaneous A, radiative transition rate &beta; and lifetime &tau;rad of Tm<sup>3+</sup> in Ge-Ga-S-CsI glasses and so on by means of Judd-Ofelt theory according to absorption spectrum were calculated. The fluorescence spectra were investigated with the different Tm<sup>3+</sup> ion concentration under 800 nm excitation. Also, the emission cross-section at 1.8 &mu;m and 3.8 &mu;m was found using the theory of McCumber and the Futchbauer- Ladenburg equation respectively.

Abstract:This paper summaries the state-of-the-art of image quality assessment (IQA) and human visual system (HVS). IQA provides an objective index or real value to measure the quality of the specified image. Since human beings are the ultimate receivers of visual information in practical applications, the most reliable IQA is to build a computational model to mimic the HVS. According to the properties and cognitive mechanism of the HVS, the available HVS-based IQA methods can be divided into two categories, i.e., bionics methods and engineering methods. This paper briefly introduces the basic theories and development histories of the above two kinds of HVS-based IQA methods. Finally, some promising research issues are pointed out in the end of the paper. &copy; 2010 SPIE.

Abstract:In this paper, we present a new scheme for parallel phase-shifting interferometry that employs a Michelson-like architecture and a simple polarization unit to generate two phase-shifting interferograms with phase shift of &pi;/2 at a single camera exposure. The parallel phase-shifting unit is built with simple optical components, and the distance between the parallel interferograms can be adjusted conveniently. Phase reconstruction is performed by using an algorithm developed for two-step phase-shifting interferometry. The practicability of the proposed configuration and the reconstruction method is demonstrated by experiments. &copy; 2010 Optical Society of America.

Abstract:In this study we report on surface crystallization phenomena and propose a solution for the fabrication of long and robust tellurite glass fibers. The bulk tellurite glasses of interest were prepared by melting and quenching techniques. Tellurite glass preforms and fibers were fabricated by suction casting and rod-in-tube drawing methods, respectively. The surfaces of the tellurite bulk glass samples and of the drawn fibers prepared under different controlled atmospheres were examined by X-ray diffraction. When the tellurite glass fibers were drawn in ambient air containing water vapor, four primary kinds of small crystals were found to appear on the fiber surface, &alpha;-TeO<inf>2</inf>, &gamma;-TeO<inf>2</inf>, Zn<inf>2</inf>Te<inf>3</inf>O<inf>8</inf> and Na<inf>2</inf>Zn<inf>3</inf>(CO<inf>3</inf>)<inf>4</inf>&middot3H<inf>2</inf>O. A mechanism for this surface crystallization is proposed and a solution described, using an ultra-dry oxygen gas atmosphere to effectively prevent surface crystallization during fiber drawing. &copy; 2010 Elsevier B.V.

Abstract:The roles of surface plasmon resonance and localized resonances in second-harmonic generation are investigated in a noncentrosymmetrical metallic film with a periodic subwavelength nanohole array. By using a recently developed microscopic classical theory and a three-dimensional finite-difference timedomain algorithm, numerical results show that the second-harmonic intensity is a function of the polarization and wavelength of incident waves. A peak of the second-harmonic intensity is achieved when the incident wave is along the direction perpendicular to the x-axis of nanoholes, which corresponds to the maximal extraordinary optical transmission. Meanwhile, the second harmonic is found to correlate with the group delay of incident waves. &copy; 2010 Optical Society of America.

Abstract:A theory model was presented, which account for the impacts of amplified spontaneous emission and double continuous-wave assist light beams on the carrier dynamics in a semiconductor optical amplifier(SOA), and was used to numerically simulate transparency wavelength shift, gain saturation and effective carrier lifetime variation. Firstly, as a verification of the model, the dependence of transparency wavelength on both probe wavelength and probe power was provided. This numerical result was in agreement with the previous experiment. Secondly, based on this temporal gain dynamics model, the SOA behaviors of gain saturation and effective carrier lifetime under double assist light beams separately near material and device transparency wavelengths were investigated. It is demonstrated that the saturation output power and the gain recovery time can be greatly improved by using double assist light injection without sacrificing the available SOA gain compared with the scheme of single assist light injection. These simulation results suggest that using double assist light beams near transparency wavelength are useful for improving SOA performance in ultrafast photonic networks.

Abstract:With the development of space optical technology, time delay and integration charge coupled device (TDI-CCD) space camera has been widely applied. TDI-CCD image sensor not only improves signal-noise-ratio(SNR) of the optical system but also makes the opto-mechanical structure of the camera more compact, but the optical system distortion will affecte image quality, so the optical system design must satisfy the new demand. The optical system distortion which affects TDI-CCD integral is analyzed. The method of image distortion elimination of space camera optical system is researched. An optical system is designed with distortion correction lens which is characterized by the spectral band of 450~900 nm, focal length of 6000 mm, and F number of 10. The result indicates that the view field angle reaches 1.6&deg;, optical system distortion is less than 0.01%. modulation transfer function reaches 0.50 at 50 lp/mm Nyquist frequency with 0.06 central obscure, and the quality of image reaches the diffraction limit. The designed optical system can meet the demand for the use of high resolution space cameras, and is suitable for multi-spectrum, stereo imaging, and stereo mapping camera system which has little distortion.

Abstract:By expanding the LP01 mode into a linear superposition of Laguerre-Gaussian modes and using Collins formula, the analytical propagation equation of wave-guide modes in a single-mode fiber through paraxial ABCD optical systems is derived. The free-space propagation and focusing properties of the LP01 mode are studied and compared with those of the fundamental Gaussian mode. It is shown that the Gaussian mode in place of the LP01 mode may introduce some errors. In the focused field of the LP01 mode there exists the focal shift which increases with decreasing Fresnel number. By a suitable choice of the Fresnel number, a long focusing depth may appear for the LP01 mode which is quite different from that of the focused Gaussian mode.

Abstract:Based on the generalized nonlinear Schro&die;dinger equation and waveguiding properties typical of the photonic crystal fiber structure, nonlinear chirped-pulse propagation and supercontinua generation in the femtosecond and picosecond regimes are investigated numerically. The simulation results indicate that an input chirp parameter mainly affects the initial stage of spectral broadening caused by the self-phase modulation (SPM) effect. In the femtosecond regime where the SPM effect plays an important role in the process of spectral broadening, an input positive chirp can enhance the supercontinuum bandwidth through a modified pulse compression phase and a decreased propagation distance required by soliton fission. In the picosecond regime, where the SPM effect contributes less to the continuum bandwidth and four-wave mixing process or modulational instability dominates the initial stage of spectral and temporal evolution, the output spectral shape and bandwidths are less sensitive to the input chirp parameters. &copy; 2010 Optical Society of America.

Abstract:The comparison between "large aperture static imaging spectrometry (LASIS)" designed by author and "method for simultaneously measuring the spectral intensity as a function of wavelength of all the pixels of a two dimensional scene" (MSMSI) designed by Israeli researchers is given. The difference of the interferometers and imaging systems in LASIS and MSMSI is discussed. The nonlinear curve of optical path difference of MSMSI is simulated. Inspired by the operation of MSMSI, the time modulated Fourier transform imaging spectrometry based on lateral shearing interferometer was presented.

Abstract:Compared with other existing methods, the feature point-based image watermarking schemes can resist to global geometric attacks and local geometric attacks, especially cropping and random bending attacks (RBAs), by binding watermark synchronization with salient image characteristics. However, the watermark detection rate remains low in the current feature point-based watermarking schemes. The main reason is that both of feature point extraction and watermark embedding are more or less related to the pixel position, which is seriously distorted by the interpolation error and the shift problem during geometric attacks. In view of these facts, this paper proposes a geometrically robust image watermarking scheme based on local histogram. Our scheme mainly consists of three components: (1) feature points extraction and local circular regions (LCRs) construction are conducted by using Harris-Laplace detector; (2) a mechanism of grapy theoretical clustering-based feature selection is used to choose a set of non-overlapped LCRs, then geometrically invariant LCRs are completely formed through dominant orientation normalization; and (3) the histogram and mean statistically independent of the pixel position are calculated over the selected LCRs and utilized to embed watermarks. Experimental results demonstrate that the proposed scheme can provide sufficient robustness against geometric attacks as well as common image processing operations. &copy; 2010 Elsevier B.V.

Abstract:A two-cavity Fabry-Perot(F-P) structure is compared to the conventional F-P structure. The characteristics of transmission spectra for the conventional and the two-cavity F-P structures are theoretically analyzed. Based on the theoretical analysis, the transmission spectra of conventional, symmetric and asymmetric two-cavity F-P structures are simulated, and the results are discussed. The results show that, while the increase of the cavity length of a conventional F-P structure results in multiple resonant peaks on both sides of the main peak, the two-cavity F-P structures of the same total length can improve spectral range effectively and keep the main peak without degrading the performance through proper design of the mirror reflectivity and cavity lengths. The mirror reflectivity also decides the full width at half maximum(FWHM) of the peaks at the central wavelength for both conventional and two-cavity F-P structures. The influences of cavity lengths and their ratio, and mirror reflectivity on transmissivity, FWHM and spectral range of the two-cavity F-P structure have been discussed.

Abstract:The dispersion of Yb-doped fiber is measured by a spectral interferometric technique. The experimental verification is achieved by comparing the measured data with published data of the Nufern 1060xp fiber and the measurement relative error is 1.36%. The parameters of the experimental system, such as minimum required source bandwidth and minimum fiber length, are introduced and analyzed in the measurement. The minimum required source bandwidth predicted through theoretical calculation at the center wavelength of 1070 nm is 19.3 nm, which perfectly agrees with the experimental value. &copy; 2010 Chinese Optics Latters.

Abstract:Spectrum broadening induced by cross phase modulation (XPM) was investigated by exploiting the optical time-division multiplexing (OTDM) data signal and continue wave probe light co-propagation in dispersion flattened high nonlinear photonic crystal fiber (PCF). The effects of wavelength drift of probe lights, polarization mismatch, total power and power ration of pump and probe light on the spectrum broadening were analyzed. The results show that good XPM effects can be obtained in 36 nm wavelength range when the total power is higher than 23 dB, power ration of pump and probe light is appropriate and with identical polarization. Furthermore, polarization independent XPM effect can be achieved by using the remainder birefringence of the PCF with the pump state of polarization (SOP) aligned at 45&deg; to the PCF principal axes. The obtained results in this paper would be helpful for research on ultrahigh-speed all optical signal processing devices exploiting the XPM in PCF for future photonics network.

Abstract:A novel microstructured polymer optical fiber (MPOF) probe for nitrites (NO<inf>2</inf><sup>-</sup>) detection was made by forming rhodamine 6G (Rh 6G)-doped cellulose acetate (CA) on the side wall of array holes in a MPOF. It was found that the MPOF probe only have a response to nitrites in a certain concentration of sulfuric acid solution. The calibration graph of fluorescence intensity versus nitrites concentration was linear in the range of 2.0 &times;10<sup>-4</sup> g/ml-5.0&times;10<sup>-3</sup> g/ml. The method possesses ease of chemical modification, low cost design, and potential for direct integration with existing instrumentation, and has been applied to the determination of nitrites in real samples with satisfactory results. &copy; 2010 Elsevier B.V.
