摘　　要：在菲涅耳公式、相位匹配条件和多光束干涉理论的基础上 ,将晶体偏光棱镜的各参量表示为合理的几何模型 ,得出了光强透射比随空间入射角的变化关系 ,并设计了验证光强透射比的实验 ,实验结果和理论推导相一致 结果表明 :胶合层间的多光束干涉对棱镜光强透射比的影响不可忽略 ,对于空气隙型偏光棱镜 ,由于空气隙间多光束干涉的影响 ,光强透射比随任意角度变化较大 ,而用胶合介质胶合的棱镜 。On the base of Fresnel refrection formulas and Snell′s law, and by using geometric model, the reflectance of light intensity and incident angle on the cut plane are obtained. Then the light intensity transmission of polarizing prisms with the incidence of random spatial light beam is studied. Both experimental and theoretical results indicate that the light intensity transmission of air-spaced polarizing prisms are affected more by the change of random spatial incident angle than dielectric-spaced polarizing prisms.
