Abstract

We propose a method for calculating the point scattering function (PSF) of an Offner imaging hyperspectrometer with a diffraction grating in the approximation of scalar diffraction theory. The method consistently takes into account limitations and diffraction of a light beam by elements of the hyperspectrometer system in accordance with the physics of image formation. The PSF of the Offner imaging hyperspectrometer is numerically simulated at various beam parameters and wavelengths. The simulation results are verified using analytical relationships, a geometrical optics approach, as well as a comparison with the related works of other researchers.
