光偏振片和波片的综合设计实验

Comprehensive Experiment Using Light Polarizer and Wave Plate

为加深学生对光偏振态的理解,提出了利用偏振分光镜、二分之一波片和偏振片等光学偏振元件,进行综合实验的设计方案。利用偏振分光镜,分离出p光和s光;旋转二分之一波片或偏振片,入射光的振动方向发生变化,p光和s光光强随之改变。此实验能加深学生对光偏振知识的理解,提高学生运用光学原理和光学器件解决实际问题的能力。

In order to deepen students’understanding of the polarization state of light,a comprehensive experiment is proposed using a polarizing beam splitter,a half-wave plate and a polarizing plate.When a beam of natural light is incident on the polarizing beam splitter,the parallel vibration is transmitted,vertical vibration is reflected.When the half-wave plate or the polarizing plate is rotated,the direction of vibration of the light changes,and the intensity of the p-light and the s-light changes too.This experiment can enhance students’understanding of light polarization knowledge and improve students’ability to use optical principles and optics to solve practical problems.
