Abstract

Abstract

The current international levels of stray light measurement technologies for a space-borne imaging spectrometer are introduced and the definition of stray light and it's source and harmfulness are discussed. The cut-off filter method, spectrum method, spectral stray light factor method, series transmission method, oxygen absorption spectra and parameter fit method, convolution method and correcting matrix method are described to compare their advantages and disadvantages in the stray light measurement, then the specific requirement of the stray light measurement of space-borne imaging spectrometer are given. Finally, the trends of development of stray light measurement for space-borne imaging spectrometers are summarized, which point out that the independent measuring method for stray light can not meet the needs of practical engineering and the compound measuring technologies will be a developing direction for stray light measurements of space-borne imaging spectrometers.
