| 摘 要： | 光学成像敏感器是卫星姿态控制分系统的重要组成部分，用于月面景象的获取，可为月面着陆器完成障碍识别、路径规划和安全区域选取等功能提供图像信息来源。为实现光学成像敏感器装星后设备功能和性能的检测，需要一种可在室内为光学成像敏感器提供月面场景信息的光学仪器。设计和研制了一种胶片式的静态光学目标模拟器，该目标模拟器以胶片作为图像源，通过积分球均匀照明系统将胶片照亮，并经由光学镜头将胶片图像投射至无穷远处，从而供光学成像敏感器接收。设计完成的静态光学目标模拟器视场≥30°×30°，入瞳直径Φ5 mm，入瞳距离为41 mm，镜头焦距44.78 mm，图像像素分辨率≤1 024×1 024，各项指标均达到了光学成像敏感器装星后光闭路试验的要求。

| Abstract: | Optical image sensor is an important part of satellite guidance,navigation,and control(GNC)subsystem,the sensor can get the moon’s image,and the image information can help the moon lander to recognize obstacles,plan paths and select safety areas.In order to realize the function and performance detection of the optical image sensor,a kind of equipment that can afford infinite optical target in the limited space is needed,which can give the moon’s image information to the optical image sensor.A static optical target simulator using films was designed and developed.The simulator used films as the image sources,the films were illuminated by an integrating sphere and the films images were projected to infinity by optical lenses,so as the images at infinity were received by optical image sensor.Results of the designed static optical target simulator show that the field view is more than 30°×30°,the entrance pupil isΦ5 mm,the distance of the entrance pupil is 41 mm,the focal length is 44.78 mm,and the image resolution is more than 1024×1024.All the indicators of the static optical target simulator can reach the requirements of the optical image sensor light closed-loop test. |
