| Abstract: | 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. |
