摘　　要：介绍了空间调制型干涉光谱成像技术的基本原理,结合为环境与灾害监测测预报小卫星研制的超光谱成像仪总体方案,阐述了该类仪器的主要技术参数设计方法,以及光学、机械、电子、定标和数据复原处理等环节的关键技术,给出了仪器在轨运行获得的部分超光谱数据,以及仪器的应用潜力。The principle of Spatially Modulated Fourier Transform Spectral Imaging technology is described in this paper. The designing methods of the main technical parameters about such instrument are presented, in combination with the general scheme of the hyperspectral imager de signed for environment and disaster monitoring and forecasting small satellite. The key technologies such as optical design, mechanical design, electronic design, calibrating design and spectral recovery are described. Finally, the hyperspectral images acquired in orbit by the hyperspectral imager are given, which show the potential application of the instrument.
