嫦娥一号干涉成像光谱仪的定标

介绍了我国首次探月卫星的有效载荷之一Sagnac空间调制型干涉成像光谱仪的定标.提出了“行”平场原理以及不同类型的光谱仪对比方法,分别用于相对定标与光谱辐射度绝对定标,取得了好的实验结果.检测了谱线位置不确定度、光谱分辨率及在轨光谱辐射度的相对不确定度.给出了探月卫星干涉成像光谱仪的定标及检测结果.首次采用干涉型成像光谱仪实现了对月的可见光/近红外宽谱段连续光谱探测.

Calibration of Chang′E-1 Satellite Interference Imaging Spectrometer

The Sagnac Spatially-Modulation Interference Imaging Spectrometer was one of the Chang’E-1 Satellite payload,The Calibration methods of it was first introduced,including Row-Flat-fields principle,and Spectrum-Contrast-Method among varied types of spectrometers,which were applied to the relative and absolute radiometric calibration of instrument.Others,the spectral position and spectral resolution were measured,and radiometric uncertainty of instrument on orbit was evaluated.The above-mentioned principles and results were first advanced both at home and aboard.The scheme of interference imaging spectrometer first successfully obtain the visible-near infrared broad spectral range and continual spectrum of the moon.
