Abstract:In order to solve the prolem of co-phasing detection for the segmented mirror of telescope, the piston errors measurement of segmented mirror by the broadband and narrow-band Shack-Hartmann algorithm are theoretical analyzed and simulated, and an active optics and co-phasing experiment system is built. The segmented mirror is consisted of four hexagonal segments with the flat to flat lengths of 100 mm and the curvature of radius is 2000 mm. Firstly, the Shack-Hartmann is used to detect the errors of co-focus, and the active optics is used to control piezoelectric actuators to realize the fine co-focus of segmented mirror. Then the broadband phasing algorithm is used to realize the measurement of corse co-phasing of segmented mirror. Finally, the narrow-band phasing algorithm is used to realize the measurement of fine co-phasing of segmented mirror, and the active optics is used to control piezoelectric actuators to realize of the segmented mirror co-phasing adjustment. The experimental results show that the range is dozens of micros and the measurement accuracy is better than 15 nm of broadband and narrow-band phasing algorithm, which demonstrates that the methods are suitable for the segmented mirror co-phasing measurement and adjustment.<br/> &copy; 2018, Science Press.

Abstract:In order to improve the modulation depth of the single layered graphene electronic controlled terahertz modulator, a terahertz transmission modulator with an arm type metal mesh structure combined with graphene is proposed. The resonant coupling field excited by the arm type metal mesh structure enhances the interaction between graphene and terahertz wave, which greatly improves the modulation depth of the terahertz modulator when the modulation voltage is applied. The influences on the interaction enhancement of graphene and terahertz wave at different metal structure parameters are analyzed by finite element method simulation. The theoretical results indicate that the arm type metal grid structure increases the modulation depth from 7.7% to 28.2%. On the basis of the theoretical results, the device is fabricated with the photolithography process. The 24% modulation depth is obtained in the experimental measurements, and the experimental modulation depth curve is basically in agreement with the theoretical simulation.<br/> &copy; 2018, Science Press.

Abstract:In order to recover the degraded image induced by the fog or haze, this paper proposes a single image dehazing algorithm based on adaptive dark channel prior. The error during the estimation of transmittance by Dark Channel Prior(DCP) will directly cause Halo effect. To deal with this problem, the notion of Adaptive Dark Channel Prior(ADCP) was proposed, it means using adaptive in the acquisition of DCP, it can reduce the effect brought by the change of depth of focus, So it will obtain the transmittance correctly without the use of Guided Filtering(GF), this means it will avoid low efficiency and defog incomplete caused by the filtering. Experiments show that the improved dehazing algorithm could eliminate the Halo effect and achieve the dehazing image with high contrast, high color saturation and abundant details from both objective or subjective image-quality assessment. Meanwhile, the speed of image process is also improved.<br/> &copy; 2018, Science Press. All right reserved.

Abstract:A pressure measurement and compensation technique was studied by employing a 3.291 &mu;m Continuous Wave (CW) Interband Cascade Laser (ICL) and a dense-patterned Multipass Gas Cell (MPGC) with an effective optical path length of 54. 6 m. The pressure inside the MPGC was measured based on direct Lorentzian absorption line fitting on the measured absorption spectral signal of CH<inf>4</inf>, and then pressure compensation was made on the masured CH<inf>4</inf>concentration. Pressure calibration was performed from 1.33&times;10<sup>4</sup>Pa to 10.64&times;10<sup>4</sup>Pa using a 2.1&times;10<sup>-6</sup>CH<inf>4</inf>sample. An Allan deviation analysis of the measured pressure of a 2.1&times;10<sup>-6</sup>CH<inf>4</inf>at 9.31&times;10<sup>4</sup>Pa pressure indicates a measurement precision of ~219.5 Pa with a 2.2 s averaging time. Fiveteen groups of pressure/concentration measurements of 1.0&times;10<sup>-6</sup>, 1.2&times;10<sup>-6</sup>, 1.4&times;10<sup>-6</sup>, 1.6&times;10<sup>-6</sup>and 2.1&times;10<sup>-6</sup>CH<inf>4</inf>samples at different pressures of 1.33&times;10<sup>4</sup>, 3.99&times;10<sup>4</sup>and 6.65&times;10<sup>4</sup>Pa were performed, and the results proved the feasibility of the proposed pressure measurement and compensation technique.<br/> &copy; 2018, Science Press.

Abstract:Perovskite quantum dots have attracted great attention due to their narrow emission spectrum, tunable spectrum and high quantum yield, however, their poor stability because of the sensitivity of water and oxygen molecules limits their application. Polymethyl methacrylate (PMMA) and polystyrene-polyethylene-polybutene-polystyrene block copolymer (SEBS) were selected as two kinds of polymer materials to study their perovskite quantum dots film performances. The high-quality perovskite quantum dots films were fabricated by one-step package method. The decay rate of PMMA perovskite films was about 4 times and 6 times that of SEBS films under continuous 365 nm UV excitation and LED remote package, which indicated SEBS perovskite films had better stability than PMMA. Furthermore, the stability of SEBS perovskite films in air and water was studied. Compared with the 18% recession after about 4 h of the perovskite quantum dots solution, it was found that SEBS perovskite films in the air and water about 18% degradation extended to 55 h and 240 h, indicating that SEBS package enhanced the stability of the perovskite quantum dots, which has great significance to the application of perovskite quantum dot package in the future.<br/> &copy; 2018, Science Press.

Abstract:In order to control the propagation trajectory of an Airy beam, generalized Airy beams are proposed theoretically. Such beams can be generated by modulating a Gaussian beam imposed on a tunable phase pattern, where two angle factors &theta;<inf>1</inf>and &theta;<inf>2</inf>are introduced in cubic phase. The hyperbolic parabola is investigated based on diffraction catastrophe theory. We focus on the non-diffracting property in the propagation distances of 0, 3, 6, 10cm in the case of &theta;<inf>1</inf>=&pi;/3 and &theta;<inf>2</inf>=7&pi;/6, and the self-healing property in the case of &theta;<inf>1</inf>=3&pi;/2 and &theta;<inf>2</inf>=&pi;/4. The experiment and numerical simulations demonstrate that such beams still possess the non-diffracting, self-healing properties to some extent, although the theory shows that they are not the solutions for paraxial wave equation. The generalized Airy beams can propagate along arbitrarily appointed parabolic trajectories and directions in free space, and their intensity distributions are different from that of traditional Airy beams, which make the generalized Airy beams have potential applications in optical trapping and biomedicine.<br/> &copy; 2018, Science Press.

Abstract:It is put forward that the solar vector (direction of the sun) can be measured through multiple polarization sensors, according to the formation principle of the atmospheric polariztion pattern. First, the formation of the atmospheric polarization pattern is introduced. Then, the polarization sensor consisting of two groups of polarization units is designed, and the optimal angle between polarization units is demonstrated, and the method of extracting the solar azimuthal information from the atmospheric polarization pattern is analyzed. Finally, with the least squares algorithm united, the method of measuring the solar vector with multiple polarization sensors is put forward, and the experiment is conducted consequently. The results indicate that it can get precise solar vector using the method proposed, and the errors of the solar azimuth angle and elevation angle are 0.2&deg; and 1.0&deg; respectively. In addition, it has solved the mutation problem which is caused by the parallelism of the maximum polarization directions measured by double polarization sensors. Therefore, the algorithm is feasible to measure solar vector with multiple polarization sensors.<br/> &copy; 2018, Science Press. All right reserved.

Abstract:The thin films of Sb-doped Silicon Quantum Dots (Si-QDs) embedded in Si<inf>3</inf>N<inf>4</inf>matrix were prepared by using muti-target radio frequency magnetron sputtering deposition technique combined with a rapid thermal process. The microstructure and luminescence properties of the films were studied by transmission electron microscopy, grazing incidence X-ray diffraction, Raman spectroscopy and photoluminescence spectroscopy. The effect of Sb doping on the microstructure and luminescent properties of Si-QDs films was discussed. The results show that the Sb-doping films exhibit obvious Sb-induced crystallization effect in annealing process. The doping of Sb contributes to the diffusion of Si atoms in the Si<inf>3</inf>N<inf>4</inf>matrix and formation of Si-QDs. With the rise of Sb doping amount, the size of Si-QDs gradually is enlarged, and the crystallinity X<inf>c</inf>of the films increases effectively. As Sb doping amount rises, the intensity of the PL peaks of the Si-QDs films enhances, and the full width at half maximum of the peaks becomes narrower. Meanwhile, due to the rise of the Si-QDs size, a red-shift is observed in the films with higher Sb doping density.<br/> &copy; 2018, Science Press. All right reserved.

Abstract:In order to monitor SO<inf>2</inf>emission from coal-fired power factories and meet national ultra-low emission standards, measurement method for low-concentration SO<inf>2</inf>via short optical length is proposed. At known pressure and temperature conditions, dataset of differential absorption cross section was constructed with various concentrations of standard gas, utilizing differential optical absorption spectroscopy (DOAS). In accordance with standard deviation and average of the dataset, combined with results of concentration inversion, spectral window was gradually reduced from 200~400 nm to 294~308 nm. For each point in 294~308 nm, where there are 137 sampling points, statistics and standard deviation were applied to characterize consistency of differential absorption cross section. It was only when standard deviation and average at sampling point met requirements that the point was reserved to optimal point set. So optimal dataset of differential absorption cross section and optimal sampling points were constructed eventually. At same pressure and temperature conditions, SO<inf>2</inf>concentration in flue gases can be accurately calculated by the optimal dataset and DOAS. In the laboratory, measurement range is 2~30 &mu;L/L, temperature and pressure are 299.05 K, 101.33 kPa, while optical length and volume of gas cell are 420 cm, 0.5 L correspondingly. Experimental results show that inversion concentration performs superior repeatability within 72 h, relative error is less than 1.7%, full scale error is below 1.3%, and zero drift is 0.09 &mu;L/L. With 420 cm optical length, the method can precisely measure low-concentration SO<inf>2</inf>under 30 &mu;L/L, resolve conflicts between concentration and optical length, which is suitable for study of ultra-low emission monitoring system used in coal-fired power plants.<br/> &copy; 2018, Science Press.

Abstract:The output characteristics of a passively Q-switched Nd: YAG/Cr<sup>4+</sup>: YAG/YAG composite crystal laser at 1064 nm was studied with diode-end-pumped system. The laser output characteristic parameters were compared among five output couplers with different transmittance, and between two Cr<sup>4+</sup>: YAG crystals with initial transmittance of 84.1% and 90.6%. The experiment results show that the output parameters as average output power, pulse repetition frequency and pulse width could be optimized with transmittance of the output coupler. And the optimized transmittance also increased with the pump power. By the comparison of laser output characteristics between two crystals with different initial transmittance, the crystal having initial transmittance of 84.9% produced relatively low average power output, but its low pulse repetition frequency and narrow pulse width made the Q-switched laser peak power improved significantly. Under the incident pump power of 10.4 W, the maximum output power of 3.2 W was obtained using the output coupler with 30% transmittance. The calculated peak power was up to 6.3 kW as corresponding pulse width and pulse repetition frequency of 9.7 ns and 52 kHz, respectively.<br/> &copy; 2018, Science Press. All right reserved.

Abstract:Aiming at the vertical large plane interferometer, the method of three-flat test with Zernike polynomials was used to study the influence of the clamping and gravity deformation of the large plane on the absolute surface test results. The method of ANSYS finite element analysis was used to simulate the clamping and gravity deformation under different parameters. The clamping parameters of the ring width of 15 mm and the plane thickness of 90 mm are optimized, and the deformation quantity peak-valley value is 0.023&lambda; (&lambda;=632.8 nm). The result of simulation experiment and comparative analysis base on the three-flat test with reference plane deformation show that the clamping and gravity deformation of the large reference plane in the vertical large plane interferometer is not only effects on the reference surface shape of the reference plane itself, but also affects the absolute surface shape of the large plane without deformation, and the surface deviation peak-valley value is basically 0.011&lambda;, so the clamping and gravity deformation influence can't be ignored. This study will provide references for future research on deformation compensation. v<br/> &copy; 2018, Science Press. All right reserved.

Abstract:Based on the surface plasmon polaritons, a Metal-Insulator-Metal (MIM) structure filter which is coupled by a square concave ring resonantor and a waveguide is proposed. The magnetic field distributions, the transmission spectrums and the resonant wavelength distribution curves of the MIM structure are obtained through the numerical simulation software which is based on the finite element method. The results show that its stopband has a minimum transmittance of 0.01 while its passband transmittance can reach up to 0.96 and the top is smooth. When the parameter I or H of the waveguide structure is increased, the corresponding transmission curve has obvious red shift and the transmittance of different stopband modes will also change. In addition, the resonance wavelength shows a linear relationship with the structure parameters. When the structure parameter D is increased, the transmittance of mode 1 increases from 0.63 to 0.80, the mode 1 disappears eventually and the other modes are almost unchanged. the resonance wavelength shows no relationship with D. After optimization of structure parameters, the quality factor of waveguide structure can be improved from 14.82 to 17.07 and the bandwidth of the passband is increased. The MIM structure filters have the advantages of small footprint size, multi-modes, narrow stopband, smooth passband, good quality factor and adjustability. Therefore the MIM structure filters may have good applications in Micro-nano integrated optical devices, especially in wavelenth division multiplexing system.<br/> &copy; 2018, Science Press.

Abstract:The Mathieu beam produced by partially coherent light was studied theoretically and experimentally, based on Fresnel diffraction theory and Fourier transform. The intensity expression of the Mathieu beam was derived with sampling theory and dispersion formula. The section intensity distribution of the Mathieu beam at different propagation distances was simulated. And the experiment was designed to verify the simulation results. We would choose multi-wavelength blue LED as the light source in the the experiment. The Mathieu beam would be obtained using a axicon and a film with an elliptical aperture. Both simulated and experimental results show that partially coherent light can produce Mathieu beams. The results provide a theory evidence for extending the application range of Mathieu beam.<br/> &copy; 2018, Science Press. All right reserved.

Abstract:The position and period of grating fringes will vary against the substrate during double beam interference exposure due to temperature variation, air flow, vibration and other factors in the fabrication of large-size holographic gratings. It will result in the decrease of grating contrast. The dynamic change of fringes was analyzed during large-size grating exposure. The Root-Mean-Square (RMS) errors of fringe translation and period in 3 hours are 1.87 and 1.20 period respectively. The corresponding simulative grating contrasts are 12.83% and 67.37% respectively. A fringe locking system composed of three monitoring subsystems, a computation and control subsystem and two piezo nanopositioners was set up. The translation and period of fringes can be locked at the same time. The groove shape and contrast of gratings are improved significantly after locking. The precision of this fringe locking system: the 3&sigma; value of fringe translation and corresponding contrast are 0.009 period and 99.99% respectively; the RMS error of period change and corresponding contrast are 0.017 period and 99.77% respectively. This locking system satisfies the requirements of fringe stability for the exposure of large-size gratings.<br/> &copy; 2018, Science Press. All right reserved.

The analysis show that the appropriate filter quality factor could enhance the system MTF after the optical design is done and the sensor is confirmed. If the optimum quality factor setting value of the filter is 1, the system MTF at the Nyquist spatial frequency can be increased by 32%. The test results show that MTF enhancement filter can improve the system imaging performance when the quality factor is 1, and the noise suppression capability is comparable to that of the maximally flat filter in passband.<br/> &copy; 2018, Science Press.

Abstract:The modulation instability generated by 2 &mu;m dissipative soliton fiber laser under high peak power is studied. The effect of nonlinear effects on the optical pulse characteristics is analyzed by calculating the dynamic process of the dissipative soliton mode-locked model. By introducing the dispersion compensation fiber into the annular cavity and adding the radius of the mode field, the net positive dispersion is enlarged and the self-phase modulation effect is reduce in the cavity. Aiming at the larger linear chirp pulse output, 46.83 m large mode area fibers is taken to compress out of cavity. Finally the stable pulse output with peak power of 17.1 kW and pulse width of 169 fs is obtained.<br/> &copy; 2018, Science Press. All right reserved.

While DC bias on the photo-cathode is -3 kV and three large aperture magnetic lens are used to image the electrons from the photo-cathode onto the microchannel plate with the image ratio of 2:1, the theoretical static spatial resolution is better than 110 &mu;m. The relationship between the spatial resolution and the point of electron emitted from the photo-cathode is obtained. While the distance of the electron emitting point to the center of the photo-cathode is increased, the spatial resolution is worse. The variation of the spatial resolution with the photo-cathode voltage is provided. The spatial resolution is improved with increasing photo-cathode voltage. In addition, the spatial resolution is better by increasing the numbers of the magnetic lens. Furthermore, it can be seen from the simulation results that the image plane is a curved surface while the photo-cathode is a plane.<br/> &copy; 2018, Science Press. All right reserved.

Abstract:Based on the four-layer plasmons structure (silicon-metal-silicon-silica), two types of optical leaky-wave-antennas that have different ellipsoid-hole array structures in the metal layer were proposed. The structures include one-dimensional symmetric tapered array and two-dimensional symmetric tapered array. Based on antenna theory and finite element method, some physical characteristics for the antennas were investigated numerically. It is found that when the operating wavelength is fixed at 1550nm, the two antennas appear ultra wide bandwidth with 80 THz that covers the band of S<inf>+</inf>-L<inf>+</inf>. With their ports filled in the air and the silicon nitride, respectively, they both show low return loss and insertion loss. But for two types of different filled materials, their characteristics show some differences, for example, in a one-dimensional symmetric structure, the antenna has less return loss and insertion loss, lower side lobe level, and better directionality when its ports is filled with silicon nitride. The antenna can be generalized to apply in the fields of optical integrated interconnection, the control of highly integrated optical beam and space optical communication.<br/> &copy; 2018, Science Press.

Abstract:The optical transfer function is accepted as an essential index to evaluate the imaging quality and is an important auxiliary parameter for designing the optical system. Based on the background oriented schlieren, the displacement field data of the light passing through the refractive index field are obtained, and the corresponding wavefront gradient data is obtained by combining the Marius theorem. Combined with the geometric optical transfer function formula, the optical transfer function can be achieved. The optical transfer function of a flat convex lens is measured by the above idea and is compared with the optical transfer function results calculated by ZEMAX. Comparison of the experimental results and theoretical results at low frequencies is conducted and the error is less than 4%. Feasibility and validity of background oriented schlieren for measuring the optical transfer function of low-pass systems are verified.<br/> &copy; 2018, Science Press. All right reserved.

Abstract:Doppler frequency shift in optical fiber is measured by fiber frequency shift interferometry, and a method of optical fiber ultrasonic sensing is obtained. The optical fiber loop wound on the piezoelectric ceramic is inserted into the frequency-shift interference Sagnac interferometer, where the piezoelectric ceramic is taken as the ultrasonic signal source, the acousto-optic modulator is adjusted so that the interference signal is biased at the zero point to reach the highest sensitivity of the system. Through the frequency and amplitude of the interference signal, the Doppler frequency shift in the fiber loop caused by ultrasound is measured, and the ultrasonic signal acting on the fiber loop is obtained. The experimental results show that, the relative error of the sensing method is 0.001% for the ultrasonic frequency measurement, and the frequency response has a good linearity in the measured range of 20 kHz to 200 kHz. There are some application prospects of the proposed method in the aspects of pipeline health monitoring, solid internal crack monitoring and structural damage monitoring of large machinery and equipment.<br/> &copy; 2018, Science Press.

Abstract:Lanthanum titanate (H4) films were deposited by the thermal vapor deposition technique. After irradiating with a 1064 nm and 532 nm lasers, the refractive index, extinction coefficient, Laser-Induced Damage Threshold (LIDT) of the films and damaging process of the films were investigated. The results showed that the refractive index of H4 films slightly increased after laser irradiating. The LIDT increased from 10.2 J/cm<sup>2</sup>to 15.7 J/cm<sup>2</sup>(5-pulse irradiation) after irradiating by using a 1064 nm laser, however, the change of LIDT of the films was unobvious after irradiating by using a 532 nm laser. For the same sample, the LIDT which measured with a 1064 nm laser was higher than that with a 532 nm laser. H4 film's damage process underwent a slow 4-stage, slight, mild, moderate and extreme damage by using a 1064 nm laser, whereas the damage process was a sudden change by using a 532 nm laser, underwent a 2-stage, moderate and extreme damage..<br/> &copy; 2018, Science Press.

Abstract:To increase the calibration frequency of Chinese optical remote sensing satellite sensor, a high-frequency calibration method based on domestic multisite was presented. And the in-flight high-frequency absolute radiometric calibration of GF-1 Wide Field of View (WFV) was conducted using this method. The theory of high-frequency calibration based on multisite was intruduced. The optimized selection principle of domestic calibration site was presented according to the parameters and characteristics of GF-1 WFV. And the temporal stability of site surface was analyzed. MODIS land and atmosphere products were used to instead of in-situ measurements to increase the amount of available calibration data. The validation of MODIS land product was conducted using in-site measurements. The high-frequency calibration of GF-1 WFV4 based on Chinese multisite was carried out, and the calibration coefficients were compared with the official calibration coefficients. The result shows that time series calibration coefficients of GF-1 WFV can be obtained using the multisite high-frequency calibration method. The calibration results of GF-1 WFV4 are in good agreement with the results of the official calibration. The relative differences of GF-1 WFV4 all bands calibration coefficients of the two methods are -0.49%, 1.33%, -1.01% and 3.86% respectively, which illustrates the availability of this method. The method can be used to improve the calibration frequency of Chinese remote sensing sensor, and timely track the changes of sensor.<br/> &copy; 2018, Science Press. All right reserved.

Abstract:In order to preserve both spectral and spatial information simultaneously in fused image, we introduce the minimum Hausdorff distance and Non-Sampled Shearlet Transform (NSST) to construct a new method for remote sensing image fusion. Firstly, Principal Component Analysis (PCA) transform is applied in the original multispectral image to obtain the first principal component, this component and the panchromatic image are decomposed by NSST respectively to obtain the corresponding low frequency subband coefficients and high frequency subband coefficients. Then, the low frequency subband coefficients are fused by sparse representation, the sparse coefficients of sparse representation are fused with the region space frequency; for the high frequency subband coefficients, the regional structure similarity is utilized, using the minimum Hausdorff distance to represent the correlation of regions and different fusion strategies are adopted according to the correlation. Finally, the fused coefficients are transformed by inverse NSST to obtain the new principal component, the new component and other higher order principal components are transformed by inverse PCA transform to obtain the fused image. In this paper, three QuickBird satellite images and one SPOT satellite image are selected for testing, the results show that compared with the traditional fusion strategy algorithms, the fusion results obtained by proposed method have better objective evaluation index and subjective visual effect.<br/> &copy; 2018, Science Press.
