In order to overcome the sampling-scene phase effect in MTF measurement of sampled imaging systems  a method using random targets is introduced to yield a phase-averaged MTF. The main potential problem of implementing this method is the fact that the stationary assumption of the random targets may be vitiated in practical measurement  especially in field test due to the ill condition. We provide an efficient model-independent way of analyzing and isolating the spectral contents arising from these additional contributions to MTF measurement. Algorithms with adaptive parameter selection were also developed for spectral estimation of the test image in order to overcome the challenge brought by the size limit of the test matrices for one certain field of view derived from the isoplantic region. The MTF measurement of a CCD video imager is used to demonstrate the measurement technique and illustrate the benefits over other methods. In order to validate the results  comparisons have been made between MTF measurements of imager implemented using this method and bar target direct measurements. 2010 Copyright SPIE - The International Society for Optical Engineering.   Analysis of the additional modulation of semiconductor lasers using optical heterodyne techniques 期刊论文  OAI收割 ieee photonics technology letters, 2008, 卷号: 20, 期号: 39817, 页码: 138-140 Zhu, NH; Zhang, BH; Wen, JM; Li, H; Li, L; Chen, W; Zhang, Y; Xie, L 收藏  |  浏览/下载：72/6  |  提交时间：2010/03/08 additional modulation  distributed feedback (DFB) laser  heterodyne technique  laser driver  thermal electric cooler (TEC) controller   Characterization of high-speed optoelectronics devices based optical and electrical spectra analyses - art. no. 68380Q 会议论文  OAI收割 2nd conference on optoelectronic devices and integration, beijing, peoples r china, nov 12-15, 2007 Wen, JM; Zhu, NH; Zhang, T 收藏  |  浏览/下载：38/0  |  提交时间：2010/03/09 frequency response  additional modulation  modulation index  chirp parameters  optical and electrical spectra analyses   Analysis of the additional modulation of semiconductor lasers using optical heterodyne techniques 期刊论文  iSwitch采集 Ieee photonics technology letters, 2008, 卷号: 20, 期号: 1-4, 页码: 138-140 作者:  Zhu, Ning Hua;  Zhang, Bang Hong;  Wen, Ji Min;  Li, Hao;  Li, Liang 收藏  |  浏览/下载：32/0  |  提交时间：2019/05/12 Additional modulation  Distributed feedback (dfb) laser  Heterodyne technique  Laser driver  Thermal electric cooler (tec) controller   基于电寻址空间光调制器的光束控制关键技术研究 学位论文  OAI收割 作者:  程煜   |  收藏  |  浏览/下载：39/0  |  提交时间：2018/12/26 光束控制  beam control  电寻址液晶空间光调制器  electrical-addressed liquid crystal spatial light modulator  附加位相  additional phase  黑栅效应  black gate effect  复振幅调制  complex amplitude modulation
