为了模拟卫星在轨全年的太阳辐照情况,检验、优化整星的杂散光抑制能力,分析了光学载荷的在轨成像条件,设计了一种基于7维扫描镜+2维折反镜+1维被测样件共计10维运动机构的扫描式氙灯太阳模拟器,并建立了它们关于照明姿态和位置的控制方程,完成了被测样件的空间环境模拟照明。实验表明,对1 700mm×2 700mm的被测样件可实现方位角为-90°~+90°、俯仰角为-29°~+42.5°的模拟照明,角精度分别可达0.2°和0.1°,位置精度优于10mm。该扫描式太阳模拟器可较精确地为部分卫星提供全年太阳照明空间环境模拟实验。
In order to simulate the solar radiation situation of satellites in orbit throughout the year, to test and optimize the stray light suppression ability of the whole satellite, the on-orbit imaging conditions of optical load were analyzed, and a 7-dimensional scanning mirror + 2-dimensional folding mirror + A total of 10-dimensional movement of the sample was measured 10-dimensional scanning xenon light solar simulator, and established their attitude and position of the lighting control equations to complete the simulated space environment simulation of the sample. Experiments show that for a sample of 1 700mm × 2 700mm, the illumination can be simulated with the azimuth of -90 ° ~ + 90 ° and the elevation of -29 ° ~ + 42.5 ° with the angular accuracies of 0.2 ° and 0.1 °, respectively °, position accuracy better than 10mm. The scanning solar simulator can provide full-year solar lighting space environment simulation experiment for some satellites more accurately.
