In order to research the control method of the static stretching membrane mirror  the surface configuration must be tested. However  membrane mirror's shape is always changed by variable voltages on the electrodes  and the optical properties of membrane materials using in our experiment are poor  so it is difficult to test membrane mirror by interferometer and null compensator method. To solve this problem  an automatic optical test procedure for membrane mirror is designed based on Hartmann screen method. The optical path includes point light source  CCD camera  splitter and diffuse transmittance screen. The spots' positions on the diffuse transmittance screen are pictured by CCD camera connected with computer  and image segmentation and centroid solving is auto processed. The CCD camera's lens distortion is measured  and fixing coefficients are given to eliminate the spots' positions recording error caused by lens distortion. To process the low sampling Hartmann test results  Zernike polynomial fitting method is applied to smooth the wave front. So low frequency error of the membrane mirror can be measured then. Errors affecting the test accuracy are also analyzed in this paper. The method proposed in this paper provides a reference for surface shape detection in membrane mirror research. 2010 Copyright SPIE - The International Society for Optical Engineering.   Application of precision harmonic gear drive in focusing mechanism of space camera (EI CONFERENCE) 会议论文  OAI收割 5th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Smart Structures and Materials in Manufacturing and Testing, April 26, 2010 - April 29, 2010, Dalian, China 作者:  Zhang X.;  Zhang X.;  Zhang X. 收藏  |  浏览/下载：31/0  |  提交时间：2013/03/25 A kind of precision harmonic gear drive in the focusing mechanism of space camera is studied  which adopt external meshing complex wave transmission mode. Wave generator is combined with an elliptic cam and a flexible bearing around it. Flexspline is a structure of single wave with the same teeth. The output shaft is supported by a single cross-roller bearing. Ball screws connected the output shaft translate the rotational motion to the linear motion  and drive the focusing mirror repeated moving along the linear guide. The output rigid wheel is connected with absolute encoder to detect displacement of focusing movement. It has the characteristics of big transmission ratio  high precision  compact structure  high efficiency and smooth running etc. According to the practical application of this harmonic gear drive in the space camera  the location relationship between the displacement of focusing structure and the focal plane movement is derived  and the system error is analyzed  its accuracy is tested with the open-loop control method. Experimental results show that transmission ratio of the instrument is 1:70  repeated positional accuracy is 2m  which meet the requirements for use. 2010 SPIE.   Degenerate four-wave mixing based all-optical wavelength conversion in a semiconductor optical amplifier and highly-nonlinear photonic crystal fiber parametric loop mirror 期刊论文  iSwitch采集 Optics communications, 2008, 卷号: 281, 期号: 21, 页码: 5415-5419 作者:  Liu, Jianguo;  Cheng, Tee Hiang;  Yeo, Yong kee;  Wang, Yixin;  Xue, Lifang 收藏  |  浏览/下载：34/0  |  提交时间：2019/05/12 Degenerate four-wave mixing  Wavelength conversion  Semiconductor optical amplifier  Highly-nonlinear photonic crystal fiber  Parameter loop mirror   Based on Householder transform of the Zernike polynomial wave front fitting method to solve active optics correction force (EI CONFERENCE) 会议论文  OAI收割 Infrared Materials, Devices, and Applications, November 12, 2007 - November 15, 2007, Beijing, China 作者:  Wu X.-X. 收藏  |  浏览/下载：30/0  |  提交时间：2013/03/25 Corrective force solving is a critical technology of the active optics. A method to solve active optics corrective force is introduced  which is based on Householder transform of Zernike polynomial wave front fitting  this method is different from the traditional least square method and Gram-Schmid orthogonal method  because it does not bring ill-conditioned polynomial without constructing normal equation  so it can avoid calculation error  wave front fitting is precision. Based on the coefficient of the Zernike polynomial and the response function of the each actuator  the stiffness matrix of the primary mirror is built  and then adopting the damp least square method to calculate corrective force. Based on this method  cp400m test mirror is simulated many times  the calculation result approve: if the Householder transform is adopted  wave front fitting is precision  the result is stabilization and corrective effectiveness is better.   大型光学镜子热弹性变形的有限元分析 期刊论文  OAI收割 激光与光电子学进展, 2005, 卷号: 42, 期号: 1, 页码: 28, 31 张德江; 刘立人; 徐荣伟; 李大汕 收藏  |  浏览/下载：1216/188  |  提交时间：2009/09/18 光学  optical mirror  一般方法  thermoelastic deformation  镜子  finite element analysis  实用技巧  wave aberration  过程  透镜  简述  热弹性  ANSYS软件   Experiment system of LAMOST active optics 会议论文  OAI收割 Glasgow, Scotland, 2004-6-21 作者:  Guoping Li;  Zhengcao Zhang;  Xiangqun Cui;  Zhengqiu Yao;  Ding-qiang Su 收藏  |  浏览/下载：35/0  |  提交时间：2013/12/23 Astronomical telescope  Active optics  Force actuator  Wave front test  Mirror support
