This paper analyzes the influence of a Wollaston beam splitter on photodetection statistics when a coherent light beam in an elliptically polarized state penetrates through the Wollaston prism. Also included as an application is a study of a heterodyne experiment on a squeezed signal with a much stronger local oscillation in a coherent state after splitting by the Wollaston prism.

a Wollaston prism. If the Wollaston prism is placed far from the back focal plane the prism only makes the rays parallel but those beams are spatially dis-placed and hence are not recombined. Therefore the Smith DIC scheme requires a special design for the microscope objective lenses such that the Wollaston prism can be incorporated within.
