Paper Abstract

The report presents the results of computer simulation of a polarimetric unit of a high spectral resolution spectrograph with fiber optic input for the 6-m telescope of SAO RAS. The module permits evaluating the polarization state of the incoming radiation. The algorithm of calculation of the instrumental polarization introduced by the BTA main mirror and matching optics of polarimetric unit is based on the Mueller matrices method. The ways of evaluation methods of the degree of polarization, azimuth angle and ellipticity of radiation transmitted through the BTA main mirror and matching optics of polarimetric unit are shown. The obtained results of computer simulation, after comparison with practical data and inevitable insignificant refinements can be taken as a basis for creation of an accurate model of the map of polarization errors introduced by the BTA main mirror and its tools.
