摘　　要：介绍了改进型 Wollaston棱镜的特点、主要参数及基于这些参数对光学系统结构的设计公式。应用 Matlab软件自编程序对分束角ε与棱镜楔角γ和光轴倾角δ之间 ,相干平面倾角η与棱镜楔角γ和光轴倾角δ之间的关系进行了计算并对结果做了分析 ,得出一些有实用价值的结论 ,克服了 Wollaston棱镜使用上的局限 。WT5BZ]The paper introduces a kind of modified Wollaston Prism, including its wedge angle γ, thickness ω, optical axis inclination angle δ, and the formulas of designing the optical system based on these parameters. Using Matlab software developed by the authors, two relational expressions indicating the inflection of the wedge angle and the optical axis inclination angle both on the splitting angle ε and the plane of apparent splitting inclination angle η were calculated. By analysing the result, some useful conclusions were obtained, and the limitation of the original Wollaston prism was conquered, therefor, extending its applications. [WT5HZ]
