摘要
经计算推导和实验,研究设计了空间调制干涉光谱仪的星上定标系统,并进行了实验室光谱测试和航天元件的多种环境测试.解决了空间调制干涉光谱仪星上定标技术的关键组件定标光源、光谱滤光片、积分球组件的技术难点.实现了全孔径、部分视场的相对光谱定标,得到了星上定标光谱和干涉图.
By calculation and experimentation,on-board calibration of SMIFTS is analyzed,and spaceflight environment characteristic of on-board calibration is tested.The key parts difficulty of on-board calibration of SMIFTS:lamp-house,spectrum filter,integrating sphere are solved.The whole-aperture,part-field comparatively wavelength calibration are achieved,and spectrum curve and Before-launch Interferogram is obtained.
