Abstract

Imaging spectral is a novel detection approach which simultaneously acquires two-dimensional visual picture and one-dimensional spectral information.The imaging spectrometer not only provides abundant data for aeronautics and astronautics remote sensing, but also offers promising applications on biomedical imaging, conservation and identification of art works,surveillance of food safety,prevention and control of plant diseases and elimination of pests,and so forth. In this paper, the snapshot imaging spectrometer using image replication based on Wollaston prisms is designed. This system includes the telescope objective, the collimator lens, the wave plates, Wollaston prisms, and the imaging lens.The imaging spectrometer system based on multi-configuration can obtain a high diffraction efficiency. Every configuration provide a kind of wave. The 16 configurations are in one mechanical structure. The system’s MTF at 56 line pairs is better than 0.75. The RMS of the spots are all in one pixel.The imaging spectrometer can obtain perfect data.
