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.   The application of spectral distribution of product of two random matrices in the factor analysis 期刊论文  OAI收割 SCIENCE IN CHINA SERIES A-MATHEMATICS, 2007, 卷号: 50, 期号: 9, 页码: 1303-1315 作者:  Jin, Bai-suo;  Miao, Bai-qi;  Ye, Wu-ye;  Wu, Zhen-xiang   |  收藏  |  浏览/下载：15/0  |  提交时间：2018/07/30 limiting spectral distribution  product of random matrices  large dimensional random matrices  factor number  time series
