First  a revised Edlen formula is employed to acquire the relation between temperature and refractive index of air  followed by introducing the fixed temperature gradient distribution among the spatial grid within the optical cavity between the reference flat and the test flat of the Fizeau interferometer  accompanied by a temperature change random function within each grid. Finally  all the rays through the air layer with different incident angles are traced by Matlab program in order to obtain the final output position  angle and OPD for each ray. The influence of different temperature distribution and the length of the optical cavity in on the testing accuracy can be analyzed through the RMS value that results from repeatable rays tracing. As a result  the horizontal distribution (vertical to optical axis) has a large effect on the testing accuracy. Thus  to realize the high accuracy figure metrology  the horizontal distribution of temperature must be rigorously controlled as well as to shorten the length of the optical cavity to a large extent. The results from our simulation are of great significant for the accuracy analysis of interferometric testing and the research of manufacturing a interferometer. 2010 Copyright SPIE - The International Society for Optical Engineering.   Composite-structure frequency selective surface with tripole elements (EI CONFERENCE) 会议论文  OAI收割 8th International Symposium on Antennas, Propagation and EM Theory, ISAPE 2008, November 2, 2008 - November 5, 2008, Kunming, China 作者:  Gao J. 收藏  |  浏览/下载：72/0  |  提交时间：2013/03/25 Two composite symmetry structure is proposed in this paper. Based on the integral equation method  the frequency response with large incident angle effect is analyzed. As a result of the numerical analysis  it is shown that the composite symmetry structure with single FSS screen is efficient to stabilize the drift of FSS resonant frequency with the steering of incident angle though transmission loss increased. Especially the structure that the FSS is embedded centrally in the dielectrics has better frequency characteristic with flat top and sharp skirts. The studies have indicated the versatility of the proposed structure. 2008 IEEE.   Study of emi 8 '' pmts for reactor neutrino experiment 期刊论文  iSwitch采集 High energy physics and nuclear physics-chinese edition, 2007, 卷号: 31, 期号: 5, 页码: 481-486 作者:  Zhong Wei-Li;  Liu Jin-Chang;  Yang Chang-Gen;  Guan Meng-Yun;  Li Zu-Hao 收藏  |  浏览/下载：19/0  |  提交时间：2019/04/23 Reactor neutrino experiment  Pmt  Quantum efficiency  Linearity  Gain and dark current  Afterpulse ratio  Incident angle effect   Study of EMI 8 '' PMTs for reactor neutrino experiment 期刊论文  OAI收割 HIGH ENERGY PHYSICS AND NUCLEAR PHYSICS-CHINESE EDITION, 2007, 卷号: 31, 期号: 5, 页码: 481-486 作者:  Zhong WL(钟玮丽);  Liu JC(刘金昌);  Yang ZG(杨长根);  Guan MY(关梦云);  Li ZH(李祖豪) 收藏  |  浏览/下载：22/0  |  提交时间：2016/06/28 reactor neutrino experiment  PMT  quantum efficiency  linearity  gain and dark current  afterpulse ratio  incident angle effect
