光学教材中有关椭圆偏振光知识的分析与解读

常见的本科光学教材中,在平面简谐电磁波的波函数形式、椭圆偏振光的旋向与两子波的相位差之间的关系、椭圆偏振光的琼斯矢量表达式等知识点上,所给出的推导过程和结论不尽相同,甚至互相矛盾,令学生迷惑、误解.结合笔者的教学经验,对以上问题进行了对比分析,对各知识点进行了深入梳理,经推导和证明,给出了明确的结论.

The analysis and interpretation of the knowledge about elliptically polarized light in optics textbooks

In the widely used optics textbooks for undergraduate students, the following conclusions and their derivation process are inconsistent, and even contradictory:(1)The wave function expression of the planar harmonic electromagnetic wave; (2)The relationship between the rotation direction of elliptically polarized light and the phase difference of two sub-waves; (3)The derivation and form of Jones vector of elliptically polarized light. These inconsistencies often make students confusing. Based on years of teaching experience in optics, we conduct a comparative analysis for these inconsistencies by proof and derivation, and draw clear conclusions for each of the above knowledge.
