High-Throughput Computed-Tomography Imaging Spectrometer and Its Simulated Experiment

Liu Liangyun Yuan Yan Xiangli Bin Li Yingcai (Space Optics Laboratory, Xi’an Institute of Optics and Precision Mechanics, The Chinese Academy of Sciences, Xi’an 710068)  
The principles and configuration of the high throughput computed tomography imaging spectrometer are introduced. Three kinds of dispersers (including direct view prism) are designed and an iterative reconstruction algorithm is described. Some simulated experiments are made, and the spectral image consisting of 61×61 spatial pixels and 13 spectral bands are obtained. The simulation results show that the theorem is correct, and that the reconstruction algorithm is efficient, convergent and reliable.
