摘要

摘要: 在星敏感器随航天器升空完成姿态测量任务之前，需在地面对其进行标定试验.为满足星敏感器更高精度标定要求，针对常规地面标定设备光学结构在应对大口径、长焦距、宽光谱需求时存在的弊端，设计了一种离轴光管作为准直光学系统，研究了离轴光管装调方法，并对像质进行了评价.重点研究了一套照明系统对星点亮度进行精确控制，采用LED阵列式背光板为光源，并利用照度计对光源亮度进行多次测试，测得的数据表明可对7个连续星等进行模拟，相邻星等间亮度模拟误差小于0.8%.所设计的光学系统可为研制深空探测星敏感器提供地面标定基础.

Abstract: Before the star sensor completes the attitude measurement task with the launch of the spacecraft, it must be calibrated on the ground. In order to meet the requirements of high precision star sensor calibration, according to the shortcomings of optical structure of conventional ground calibration equipment for large aperture, long focal length and wide spectrum requirements, an off-axis collimator was designed as a collimating optical system. The alignment method of the off-axis collimator was discussed, and the image quality was also evaluated. A set of lighting system is designed to precisely control the star point brightness. The LED array backlight is used as the light source, and the brightness of the light source is tested by an illumination meter. Experimental results show that seven consecutive magnitudes can be simulated, and the simulated error between neighboring magnitudes is less than 0.8%. The designed optical system can provide the ground calibration foundation for the development of deep space exploration star sensor.
