Measurement of optical mirror with a small-aperture interferometer

Frontiers of Optoelectronics 2012年第2期5卷 218-223页

作者： Ya GAO Hon Yuen TAM Yongfu WEN Huijing ZHANG Haobo CHENG School of Optoelectronics Beijing Institute of TechnologyBeijing 100081China Department of Manufacturing Engineering and Engineering Management City University of Hong KongHong KongChina

In this paper, the principle of subaperture stitching interferometry was introduced. A testing stage with five degrees of freedom for stitching interferometry was built. A model based on least-squares method and error averaging method for data processing was estab- lished, which could reduce error accumulation and improve the precision. A 100ram plane mirror was measured with a 50mm aperture interferometer by means of stitching interferometry. Compared with the results by a 100 mm interferometer, peak to valley （PV） and root mean square （RMS） of the phase distribution residual are 0.00382 and 0.00042, respectively. It proved that the model and method are helpful for large optical measurement.

THE STUDY ON AUTOMATIC REGISTRATION OF INSAR IMAGES

引用

Geo-Spatial Information Science 1999年第1期2卷 30-34页

作者： Liao Mingsheng Zhang Zuxun Zhang Li Zhang Jianqing National Laboratory for Information Engineering in Surverying Mapping and Remote Sensing WTUSM Wuhan China

Interferometric Synthetic Aperture Radar (InSAR) allows production of high resolution DEM and detection of small earth motions using multiple pass SAR data sets obtained by remote sensing satellite. But the whole process has not yet reached sufficient robustness to warrant automated DEM production as commonly produced by stereovision with optical images. The automatic algorithm for precision registration is one of the bottlenecks in InSAR data processing. In this paper, an automatic approach with multi-step image matching algorithm is presented. All procedures are automatically implemented. The experiment is carried out successfully with SIR-C/L-band InSAR data. The triangular piecewise rectification is also advanced in reducing local distortion between the images and processing the large scene image. The primary result has prospect in the precision registration for the repeat-track InSAR data and reveals the potential of the presented automatic strategy.

DENOISING METHODS IN INTERFEROMETRIC SAR IMAGES PROCESSING

引用

Chinese Journal of Aeronautics 1999年第2期12卷 25-30页

作者：袁运能胡庆东毛士艺

Thermal and “Speckle” noise is an obstacle to generate the digital elevation model(DEM) from interferogram by 2 D SAR images. According to the theory of interferometry, the main sources of noise in interferogram are discussed. On the basis of the character of noise in the interferogram, the low pass filter, median filter and wavelet transform are investigated. Wavelet transform is forwarded as the most effective method to eliminate the InSAR noise because it can keep the resolution of the images during eliminating the noise. The raw data verify the validity and effectiveness of wavelet transform.

Accurate reconstruction of electric field of ultrashort laser pulse with complete two-step phase-shifting

引用

High Power Laser Science and Engineering 2019年第1期7卷 92-98页

作者： Yi Cai Zhenkuan Chen Shuiqin Zheng Qinggang Lin Xuanke Zeng Ying Li Jingzhen Li Shixiang Xu Shenzhen Key Laboratory of Micro-Nano Photonic Information Technology College of Electronic Science and TechnologyShenzhen University International Collaborative Laboratory of 2D Materials for Optoelectronics Science and Technology Engineering Technology Research Center for 2D Material Information Function Devices and Systems of Guangdong ProvinceShenzhen University

This paper presents a complete two-step phase-shifting(TSPS) spectral phase interferometry for direct electric-field reconstruction(SPIDER) to improve the reconstruction of ultrafast optical fields. Here, complete TSPS acts as a balanced detection that can not only remove the effect of the dc term of the interferogram, but also reduce measurement noises,and thereby improve the capability of SPIDER to measure the pulses with narrow spectra or complex spectral *** prisms are chosen to replace some environment-sensitive optical components, especially reflective optics to improve operating stability and improve signal-to-noise ratio further. Our experiments show that the available shear can be decreased to 1.5% of the spectral width, which is only about 1/3 compared with traditional SPIDER.

Consistency proof of two denoising methods and the parameter selection of PDE f iltering method for ESPI

Chinese Optics Letters 2013年第12期11卷 33-38页

作者：肖志涛袁泉张芳吴骏耿磊徐振北习江涛 School of Electronics and Information Engineering Tianjin Polytechnic University School of Electrical Computerand Telecommunications EngineeringUniversity of Wollongong

Electronic speckle pattern interferometry （ESPI） is a nondestructive, whole-field optical measurement technique. The removal of speckle noise is fundamental to extract measurement information accurately. In this letter, two filtering methods based on the oriented feature of ESPI fringes, i.e., the second-order oriented partial differential equation （SOOPDE） and oriented, regularized quadratic-cost function filtering methods, are first proven to be consistent. An important question in solving partial differential equation, i.e., how to select suitable parameters in an adaptive manner, is then discussed. The computer-simulated and experimentally obtained ESPI fringe patterns and phase map are processed by the SOOPDE filtering model with adaptive selective parameters. The qualitative and quantitative analyses demonstrate that the parameters selected by the adaptive method are effective and suitable for the SOOPDE filtering model.
