摘　　要：为阐明渥拉斯顿棱镜偏振分光原理、获取光线分离角与棱镜参数的量化关系式,基于通过惠更斯作图法,依次展示了偏振光入射到渥拉斯顿棱镜第一界面、两块三棱镜交界面以及最终出射面过程中,o光和e光的波面形状及波线方向,着重分析了从两块三棱镜交界面出射过程中o光和e光相互转换的原因与规律。作图过程和结论可为正在开展相关思考的师生及科技工作者提供一定参考。In order to clarify the polarization splitting principle of Wollaston prism and obtain the quantitative relationship between the light separation angle and the prism parameters,the wavefront shape and the wave line direction of o light and e light in the process of polarization light incident on the first interface of Wollaston prism,the interface of two triangular prisms and the final exit surface are sequentially displayed by Huygens drawing method.The reasons and regulations of the conversion between o light and e light in the process of exit from the interface of two or triangular prisms is emphatically analyzed.The drawing process and conclusion can provide some reference for teachers,students who are carrying out relevant thinking and scientific and technological workers.
