一种Wollaston式偏光棱镜分束特性的研究
Analysis of beam-splitting characteristics of Wollaston-type polarizing prisms
摘要
Abstract
In order to analysis systematically the splitting characteristics of a Wollaston-type symmetric beam-splitting prism,by using refractive formula and Fresnel formula and taking 632.8nm for example, relationship curve among the angle of emergent light to the horizontal direction,deviation angle and structure angle,relationship curve between intensity splitting beam ratio and structure angle,relationship curve among incident angle,splitting beam angle of the prism and emerging light symmetry were gotten. The results show that, strict symmetric beam can be achieved through the correction of output face of Wollaston prism. Splitting angles of o light and e light mainly depend on the prism structure angle. The effect of deviation angle is smaller. The changing magnification of beam splitting ratio with the increase of structure angle is small. When the incident angle is small, it has main effect on the symmetry of prism splitting angle. When incident angle changes between-3°and+3°, the asymmetry degree of two beam is less than 6°,which can guarantee good effect of symmetry beam splitting. The study provides a theoretical guidance for design and application of the prism.关键词
