Annotation
An optical schematic of the Stokes polarimeter developed for the high spectral resolution spectro-graph of Large Telescope Azimuthal is presented. The passport errors of the phase plates used in the polarimeter are given. A model of the phase plates operation based on Muller matrices is described and discussed. A comparison of the model with the results of measurements of the fabricated phase plates is carried out. The instrument polarization of the manufactured phase plates is estimated. Произведена оценка инструментальной поляризации фазовых пластин. As a result of numerical simulation, the er-rors of the Stokes parameters measurements are obtained.
