摘　　要：本文研究了在渥拉斯顿偏振器的两单晶介质界面上的边界条件，并给出表述光强密度、透射系数与相对位移的表达式，它不仅有助于对渥拉斯顿偏振器的光学特性的深入了解，而且对设计高分辨率和高对比度的激光光学系统有较大的指导意义。This paper examined the boundary condition at the interface of two uniaxial media contained in Wollaston prism.and the general solutions of light propagation through the interface are obtained.Based on the analySis,the relationships among the propeties of transimission coefficient,outputangle and phase shift are examined.The reSults show that Wollaston polarizer can not only product theinterference pattern with high contrast and high resolution,but also hold the high imal quality of axialray.So Wollaston polarizer can be wide used in imaging system,laser interferometer,laser polarizer.
