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.
