As being the basic testing and calibration equipment  the large aperture collimator's accuracy should be much higher than the device under testing in order to ensure the accuracy of the measurement. However  the process of adjusting the collimator is extremely complicated due to the collimator's large aperture and long focal length. So it is difficult to ensure the measurement's quality and easy to cause the system being vulnerable to the surrounding environment. One of the most common problems is defocus. In order to solve the problem above  this issue presents a new type of autocollimator autofocusing system which uses pentaprism instead of using large-aperture plane mirror  semiconductor lasers as light source and CCD sensor as receiver. The system is smaller  lighter  and more convenient when using. The computer simulation shows that the autofocusing system's resolution could reach the accuracy of 40m. If we use the relevant algorithms to execute the sub-pixel scanning  the resolution could reach the accuracy of 10m. It shows that the system could satisfy the required testing precision of testing large aperture optical device.   The design of computer-generated holograms for testing unsymmetrical optical surfaces (EI CONFERENCE) 会议论文  OAI收割 2012 International Symposium on Photonics and Optoelectronics, SOPO 2012, May 21, 2012 - May 23, 2012, Shanghai, China 作者:  Zhang X.;  Zhang Y.;  Zhang X.;  Zhang X. 收藏  |  浏览/下载：26/0  |  提交时间：2013/03/25 It is a technical difficulty to test the unsymmtrical optical surfaces in non-contact methods. But we can do it using computer-generated holograms (CGH). The principle and design of the CGH have been discussed in the paper. Take the cubic suface as an example  The order separation of the CGH is analyzed theoretically and the simulation result of the order separation is given in the paper. We develop the binary process of the continuous CGH phase function and get the sample of the amplitude CGH. A CGH for testing a cubic phase plate with duty cycle 0.5 is fabricated by using e-beam lithographic techniques. In this situation  the contrast of the interference fringe pattern can achieve a level of 99.4% by calculation. 2012 IEEE.   The optical design of cubic phase plate testing system (EI CONFERENCE) 会议论文  OAI收割 2011 Symposium on Photonics and Optoelectronics, SOPO 2011, May 16, 2011 - May 18, 2011, Wuhan, China 作者:  Zhang X.;  Zhang X.;  Zhang X.;  Zhang Y. 收藏  |  浏览/下载：19/0  |  提交时间：2013/03/25 Computer-generated holograms (CGH) have been widely used for years in optical testing of aspheric surfaces in combination with Fizeau interferometers. With the development of diffraction optics  computer technology  and micro-processing technology  the accuracy of the CGH testing can achieve a hundredth of a wave  and the cost is reduced greatly. CGH is capable of producing an optical wavefront with any desired shape. So it is fascinating and will have good prospects to test free-form surfaces using CGH. As the CGH can create any wavefront shape  it can also be used in unsymmetrical aspherical surfaces testing. Taking the cubic surface as an example  this paper gives a method to test unsymmetrical surfaces. This paper gives the design to test a cubic surface. And the separation of the diffraction orders and the binary process of the continuous CGH phase function are discussed in detail. The alignment tolerance of the test system and the CGH fabrication tolerance are analyzed. We also present an idea using a CGH and two spherical lenses as null lens to test the cubic surface when the surface deviation is great. 2011 IEEE.   Structural analysis of multiphase La1-xSrxCo 1-xFexO3-δ 会议论文  OAI收割 1st Annual Meeting on Testing and Evaluation of Inorganic Materials, Nanchang, China, APR 28-30, 2010 作者:  Gu YJ;  Yang ZN;  Chen YB;  Liu HQ;  Wu HK 收藏  |  浏览/下载：30/0  |  提交时间：2013/02/26 Materials testing  Rietveld method  Sol-gel process  Structural analysis  High-speed  Multiphase  Orthorhombic structures  Sol-gel methods  Space Groups  Structure geometry  Structure parameter  Structure refinements  Trigonal structures   Measurement of phosphate anion based on optical fiber evanescent wave sensor 期刊论文  OAI收割 guangdianzi jiguang/journal of optoelectronics laser, Guangdianzi Jiguang/Journal of Optoelectronics Laser, 2011, 2011, 卷号: 22, 22, 期号: 11, 页码: 1683-1687, 1683-1687 作者:  Wang, Zhen-Zhen;  Zhou, Jing-Tao;  Wang, Chun-Xia;  Kan, Qiang;  Chen, Hong-Da   |  收藏  |  浏览/下载：20/0  |  提交时间：2012/06/14 Composite structures  Concentration(process)  Electromagnetic wave reflection  Hydrofluoric acid  Ions  Optical fibers  Sensors  Testing  Composite Structures  Concentration(Process)  Electromagnetic Wave Reflection  Hydrofluoric Acid  Ions  Optical Fibers  Sensors  Testing
