摘　　要：通过分析探测器在相同面积条件下的矩形像元与六边形像元,优化光电成像系统设计。利用互信息量对矩形像元和六边形像元分析,得到系统仿真曲线,对光电成像图像的精细程度做定量的描述。综合考虑光学成像系统与成像探测器阵列达到最佳匹配,提出光电成像系统优化设计方法。This paper optimized the design of the optical imaging system through the analysis of the detector in the same area under the conditions of the rectangular pixel and hexagonal pixels.The computer simulation curve has been demonstrated by analyzing rectangle pixel and hexagon pixel according to mutual information,which is a scientific description for the photoelectric imaging system.Take into account the excellent matching between optical imaging system and the array of imaging sensor,the optimizing design method of photoelectric imaging system is proposed.

关 键 词：矩形像元 六边形像元 互信息量 空间频率响应
