Modeling action of a hyperspectrometer based on the offner scheme within geometric optics
Computer Optics, 2014 We considered comparative modeling action of a hyperspectrometer based on the Offner scheme including prisms or a diffraction grating within the geometrical optics. It is shown that the use of a diffraction grating instead of a prism results in a more uniform spread of the spectral components of the dispersed image.

Simulation of a hyperspectrometer based on linear spectral filters using vector bessel beams
Computer Optics, 2014 We discuss the simulation of a hyperspectrometer based on the use of linear variable filters. The possibility of recovery of the image spectral pixels through the solution of the integral equation is considered. Estimates of the scattering spot size as a function of the spectral filter parameters are obtained.

Modeling the performance of a spaceborne hyperspectrometer based on the offner scheme
Computer Optics, 2015 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
