摘　　要：光学遥感相机的静态传递函数测试需要配套适当口径的平行光管,制造难度大、成本高,无法满足高性能、低成本的商业遥感载荷研制需求。文章提出一种基于异视场准直光路的像质评价方法,使用相机光学系统自身光路作为测试系统,通过异视场光路的准直,测得相机异视场叠加像质,对测试结果进行数据解算,最终得出相机各视场的真实波前信息。以北京三号B卫星相机研制过程为例,利用相机光学系统与自准直反射镜系统配合,采用上述异视场共光路测试方法,测量结果与传统方法测试结果进行对照,结果表明该方法测试结果准确、切实可行。The transmission test of optical remote sensing camera needs parallel optical tube with appropriate aperture,which is difficult to manufacture and high cost,and cannot meet the development demand of high-performance and low-cost commercial payloads.This paper proposes an image quality evaluation method based on the collimating optical path of different field of view.The optical path of the camera optical system own is used as the test system,and the superimposed image quality of the camera is measured through the collimation of the different field of view optical path.The testing results are analyzed and the true wave front information of each field of view of the camera is ultimately obtained.Taking the development process of BJ-3B satellite camera as an example,the camera optical system and auto-collimating mirror system were used in conjunction with the above out of view common optical path test method.The measurement results were compared with the traditional methods,and the results show that the test results of the method are accurate and practical.
