Star sensor stray light test system based on real starry sky

The invention relates to a star sensor stray light test system based on the real starry sky. The system comprises a solar simulator, an irradiation beam shaping device, an optical path turning device,a tooling table board, a skylight device and a test computer device. Therefore, stray light is injected into a star sensor shading hood at a given angle under the starry sky background condition andthus a test task of the stray light test is performed. The technical means is provided for the factory test of the star sensor product; and the quantitative test and quantified evaluation of the starsensor performance are completed. 本发明涉及一种基于真实星空的星敏感器杂散光测试系统，包含太阳模拟器，辐照光束整形装置，光路转折装置，工装台面，天窗装置和测试计算机装置，可实现星敏感器处于星空背景条件下，杂散光按给定角度射入星敏感器遮光罩内，进行杂散光测试的测试任务，为星敏感器产品的出厂测试提供技术手段，完成星敏感器性能的定量测试和量化评估。
