In order to solve the problems of slow scanning speed of traditional dispersive hyperspectral imagers and the problems of information loss, signal distortion, and high reconstruction complexity in the coded aperture spectral imaging system, in this paper, a slit spectral imaging system based on a uniformly distributed array is designed. On the basis of the coded aperture spectral imaging system, a displacement motor is used to control the slit array code plate to perform field-of-view spectrum non-aliasing micro-scanning to realize the non-destructive detection of dynamic scenes. The simulation results show that the collection efficiency of this method is 17 times that of the single-slit system, and the systems spectral data reconstruction result is consistent with that of the single-slit system. The spatial structure similarity is 1.8 times and the spectral fidelity is 1.17 times of that of the 50% sampling rate coded aperture system. Finally, the system was verified by experiments.
