Simulation of hyperspectrometer on spectral linear variable filters
Computer Optics, 2014 Article is devoted to simulation of hyperspectrometer based on the use of linear variable filters. We regarded possibilities of recovery of spectral pixels of images based on the solution of the integral equation. The paper presents estimates of the size of the scattering spots depending on the parameters of the spectral filter.

Analytical calculation of diffraction order intensities for a hyperspectrometer
Journal of Physics: Conference Series, 2019 Abstract We employ a geometric optics approach to calculate the eikonal of a light field at the output of a diffraction grating in the immediate microrelief vicinity. Analytic relations to calculate the diffraction order intensities as functions of the grating step height, line spacing, wavelength of incident light, and incidence angle ...
