H. 收藏  |  浏览/下载：17/0  |  提交时间：2013/03/25 A new technique is demonstrated for measurement of modulation transfer function (MTF) on image sensor arrays. Fourier analysis of a low frequency bar target pattern is used to extract MTF at odd harmonics of a target pattern frequency up to and beyond Nyquist. The technique is particularly useful for linear image arrays (either conventional linescan or time-delay-integration devices) where conventional slanted-edge technique is not always applicable. The technique is well suited to simple implementation and can provide live presentation of the MTF curve  which helps to ensure optimal alignment conditions are achieved. Detailed analysis of the technique and demonstration of experimental results are presented. 2010 SPIE.   Expansion of urban area in the Yellow River zone, Inner Mongolia Autonomous Region, China, from DMSP OLS Nighttime Lights Data 会议论文 Qi X.
