Abstract:
This article deals with modeling of a hyperspectrometer based on the Offner scheme within geometric optics. We show that at a certain set of parameters, the geometric aberrations are small compared with the size of a conventional CCD matrix sensor. An integral equation for the reconstruction of spectral components of the signal under the overlapping of spectral orders is derived.

Keywords:
hyperspectrometer, Offner scheme, dispersing element, spectral components of an image, ray tracing.
