Abstract:The imaging spectrometer combining image and spectrum is an optical sensing instrument. It is used to obtain the detail spectrum of the objects on earth for the radial information of the land and ocean, the inspection of atmosphere and so on. The imaging spectrometer is characterized by multiple wavebands, discontinuous wavebands and position overlapping coupled with the problem of image resolution and spectrum resolution, so the optical system of the imaging spectrometer is very complicated and demanded spectrum resolution is higher than imaging resolution. The principle, design method and composition of the optica system are introduced in detail. The reasonable structure and design results based on the existing technology is given, which is novel and practicable.
Keywords:imaging spectrometer  spectrum scanner  optical system
