关于光学课程中偏振概念讲解的几点建议

Some suggestions on the introduction of polarization concept in optics

偏振是光学课程中的一个重要然而不容易讲清楚的基本概念.本文建议在偏振概念的讲授过程中,对迎光矢量图的坐标系、物理量、约定的观察方向进行细致地讲解,作为拓展知识还可以介绍标量光场和矢量光场的概念,以帮助学生全面、准确地掌握偏振的概念.

Polarization is an important basic concept in optics courses,however,it is not easy to understand.In this paper it is suggested that during the introduction of the concept of polarization,the coordinate system,physical quantity and observation direction of light vector diagram should be explained in detail.As an extension of knowledge,the concepts of scalar beam and vector beam can also be introduced to help students grasp the concept of polarization comprehensively and accurately.
