| 摘 要： | 为了分析自然光斜入射格兰式分束棱镜时光强分束比随入射角度、棱镜结构角及入射波长的变化关系,根据几何关系、菲涅耳公式及相位匹配条件从理论上推导出光强分束比的数学表达式,并通过了实验验证。结果表明,光强分束比随入射角度、棱镜结构角及波长变化呈非线性关系。所得结果为格兰式棱镜在光学器件应用中提供了有用的信息。

| Abstract: | In order to analyze the relationships of the light intensity splitting ratio with the incident angle,the prism's structural angle and the incidence wavelength's variation with the light beam coming from natural light's oblique incidence to Glan polarizing splitting prism,the mathematical formula of the light beam are deduced according to the geometric relationship,Fresnel formula and phase matching conditions.Through the analysis,a conclusion is drawn that the light beam assumes the nonlinear relationship w... |
