光电成像系统性能参数MRC及其测量方法

Electro-Optical Imaging System Performance Parameter MRC and its Measurements

与传统光电成像系统成像质量的评价方法比较,最小可分辨对比度 MRC 能够更全面地反映光电成像系统的极限性能。本文介绍了两种适合于 MRC 测试的条纹目标场景平台,可以实现空间频率、对比度以及场景平均亮度的可控变化,为减小主观测试所带来的人为因素影响,介绍了心理测量方法和 AMRC 客观测量法。这些测试系统和方法对于光电成像系统 MRC 模型及其测量方法研究具有实际意义。

Compared to traditional quality evaluation methods for Electro-Optical (E-O) imaging system, MRC could be able to describe the limited performances of E-O imaging system more generally. Two kinds of stripe target scene platform for MRC measurement are introduced ,which could implement controllable changes in spatial frequency, contrast and scene average luminance .For decreasing artificial effect factors from quality evaluation, Psychology measurement and AMRC objective measurement methods are imposed. These measure system and methods had the practical meaning to researches for E-O imaging system MRC model and its measurements.
