Analysis of Wollaston polarizer in imaging systems

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 image quality of axialray.So Wollaston polarizer can be wide used in imaging system,laser interferometer,laser polarizer.
