In this paper  a micro Fourier transform infrared spectrometer (FTIR) based on spatial modulation mode was designed. This spectrometer has the advantages of high stability and simplified configuration. It also promises optical path differences (OPD) with high precision  as MOEMS technology is used in manufacturing the key components. The simulation and the experiments with regard to this FTIR configuration have been done. Firstly  the diffraction effect of the micro multi-step mirrors (MMSMs) is studied. We discuss the influence to the reversed spectrum by different mirror widths and different diffraction distances. Secondly  we simulate and analyze the influence of the source solid angle to the spectral resolution. Thirdly  we set up the theoretical model of the collimation error which is mainly from the defocus of the optical system and analyze the result caused by the collimation error. Fourthly  a new discrete Fourier transform arithmetic using least-squares cosines progression (LSCP) is proposed which can reconstruct the spectrum with nonuniform sampled signals. Finally  the MMSMs are fabricated used the MOEMS technology and the structural parameters are tested. 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).   激光光束实时监测与自动准直系统设计 期刊论文  OAI收割 光学学报, 2008, 卷号: 28, 期号: 8, 页码: 1590, 1595 尉鹏飞; 刘军; 李晓芳; 陈晓伟; 刘鹏; 李儒新; 徐至展 收藏  |  浏览/下载：1693/284  |  提交时间：2009/09/18 光学设计  Adaptive collimation  实时监测  Beam direction  自动准直  Otpical system design  程控  Program control  Real-time monitoring   Study on technology of orientation and north-finding based on fiber optic gyroscope (EI CONFERENCE) 会议论文  OAI收割 2007 IEEE International Conference on Mechatronics and Automation, ICMA 2007, August 5, 2007 - August 8, 2007, Harbin, China Zhang Z.; Sun J.; Wu K. 收藏  |  浏览/下载：15/0  |  提交时间：2013/03/25 North-finding system provides true north azimuth information to all kinds of ground-based equipment. A dynamic automatic north-finder based on the modulation output of fiber optic gyroscope (FOG) is presented in this paper. In this scheme  the sine output signal of the FOG was sampled and disposed  and then the real north of surveyed point on the surface of earth was calculated. The deviation caused by the platform base tilt was compensated by an accelerator  Allan standard deviation is used to analyze the random drift of FOG  and establish the random error mode of FOG. The FOG north-finding and laser collimation theodolite are assembled to achieve orientation and aiming integral  which lays foundation for switching to project application. 2007 IEEE.
