Abstract
The article deals with the issues of computer simulation of the processes of spectral image formation in a hyperspectral system based on the Fabry-Perot interferometer, designed to work in the visible spectrum. A mathematical model of a hyperspectral system and its main variable parameters for evaluating the obtained characteristics of spectral selectivity are considered. A block diagram illustrating the simulation process is given. The results of computer simulation are presented. The characteristics of spectral selectivity obtained by computer simulation are given, depending on the air-gap distance between the mirror plates of the Fabry-Perot interferometer at a fixed angle of incidence of the radiant flux. The possibility of singlechannel and three-channel registration of spectral responses of the interferometer corresponding to RGB channels of a standard color matrix photodetector is shown. The variants of the structural schemes of the hyperspectral system are analyzed based on the existing compromises between the sensitivity of the system, its spectral selectivity, speed, accuracy, resolution, and complexity of implementation.
