Optical Design of Spaceborne Shortwave Infrared Imaging Spectrometer with Wide Field of View
Based on the requirements of shotwave infrared imaging spectrometer with wide field of view, considering the restrictive off-the-shelf detectors, a split field of view (FOV) method was developed. The principle of split field of view was analyzed. A spaceborne shortwave infrared imaging spectrometer with wide field of view was designed using the method. The imaging spectrometer are composed of a 11.42° telecentric off-axis three-mirror anastigmatic telescope and two offner convex grating spectral imaging system. Ray tracing, optimization and analyzing were performed by CODE V and ZEMAX software. The analyzed results demonstrate that the modulation transfer function for different spectral band is more than 0.7 which satisfies the pre-designed requirement.
