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.
