摘要: 为实现对星敏感器光谱探测能力的测试和标定, 研制了一套可模拟恒星光谱的地面标定系统, 要求其光谱模拟精度优于10%. 采用光谱分布可控、光强可调的模拟照明系统作为地面标定系统的核心器件来模拟恒星光谱变化, 设计高成像质量准直光学系统使模拟星图成平行光出射, 在光学系统出瞳处产生星图, 完成具有恒星光谱信息的高精度星图模拟. 进而利用Lighttools建立标定系统的光谱仿真模型, 仿真结果表明恒星光谱模拟精度优于10%.Abstract: In order to realize the testing and calibrating of star sensor spectral detection capability, a set of ground calibration system which can simulate the stellar spectra is developed, and the stellar simulation accuracy is required to be better than 10%. Spectral distribution controllable and light intensity adjustable light simulation system is adopted to be the core device to simulate changes in stellar spectra, collimating optical system with high image quality is designed to make the star map exit parallel light and present the star map at the exit pupil of optical system, then the high accuracy star map simulation with stellar spectra information is completed. Finally, using Lighttools, the spectral simulation model of calibration system is established and simulation results show that the stellar spectra simulation accuracy is better than 10%.
