Performance Calculations of Hyperspectral Instrument with Prismatic Dispersive Device

In recent years, all over the world the authors have noted the appearance of growing number hyperspectral instruments installed on the aircraft and space vehicles. A spacecraft hyperspectral instruments has already been on orbit of the Moon and Mars. During the design process instruments after development of the main schematic design and constructive decisions it is necessary to assess their impact on formed image and confirm stated tactical and technical characteristics. The authors have proposed a method of determining the characteristics of hyperspectral imaging instrument (angular and linear dispersion, spectral resolution, the modulation transfer function, the curvature of the spectral lines) based on the model of instrument function and raytracing through an optical system of hyperspectral imaging instrument with a prismatic dispersive device.
