介绍了高通量层析成像光谱仪的基本原理和原理装置,并且提出了直视棱镜等三种色散方案。设计了基于分块矩阵的迭代算法,降低了丢失锥体对重构数据立方体的影响。通过计算机仿真实验,得到了61×61的空间分辨率和13个波段的光谱像,试验结果证实了该原理是正确的,算法是快速、收敛、可靠的。

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.
