Paper Abstract

We introduce our latest research of the computed tomography Fourier transform imaging spectrometer that combines the advantages of both the computed tomography imaging spectrometer and the Fourier transform imaging spectrometer. In our previous work, there were still some problems such as the optical aberration in the optical system. Therefore, some significant improvements are made on the optical configuration of our new system. In this paper, the computational simulation of our new system is introduced. Both the interferogram-projection cube and the spectrum-projection cube are generated in the simulation experiment, and the filtered back projection algorithm is adopted in the image reconstruction. The results of the simulation demonstrate the feasibility of our new system.
