Polarimetric studies in astronomy have currently acquired great importance. They are used to study magnetic fields of stars, determine the orientation of orbits of exoplanets, reflection effects in stellar atmospheres and accretion disks, and many other things. This paper presents a computation of optical arrangements of Stokes polarimeters with different polarization analyzers. A preliminary estimate of the transmission of polarimeters with a Wollastone prism and with a modified Foster prism as polarization analyzers is reported. Transmission estimates were performed for different shapes of rectangular output slits and separations between them in two spectral ranges. Recommendations are provided concerning the use of Wollastone and Foster prisms in Stokes polarimeters designed for astrophysical studies.

使用不同的偏振分析仪评估斯托克斯旋光仪的效率

目前,天文学的极化研究已变得非常重要。它们用于研究恒星的磁场,确定系外行星轨道的方向,在恒星大气层和吸积盘中的反射效应以及许多其他事物。本文介绍了使用不同的偏振分析仪对斯托克斯偏振计的光学布置进行计算。报道了用沃拉斯顿棱镜和改进的福斯特棱镜作为偏振分析仪对偏振计的透射率的初步估计。对矩形输出缝的不同形状及其在两个光谱范围内的分离进行了透射率估计。提供了有关在斯托克斯旋光仪中使用Wollastone和Foster棱镜进行天体物理学研究的建议。
