【摘要】 随着微光增强型电荷耦合装置(ICCD)成像系统的广泛应用,其像质评价及测试方法日益受到人们的关注。基于离散成像系统局域等晕条件的扩展定义,本文采用狭缝离散采样+数字Fourier变换方法实现了微光ICCD成像系统调制传递函数(MTF)的测量,并结合反射式电视测试图做了一组比较实验。实验结果表明,测量方法和测量结果都是可靠的。更多还原

【Abstract】 Further applications of ICCD imaging system attract more attention to its imaging quality evaluation and methods of measurement. Based on the extended definition of local isoplanatism of discrete imaging system, a method of discrete sampling digital Fourier transform was introduced in this paper. With the help of the above measurement, the measurement of modulation transform function (MTF) of ICCD imaging systems was accomplished. A set of comparability experiments using test charts of reflection for television radiation stripe tests was also given. The experimental results indicate that the method and the results of measurement are reliable.更多还原
