摘要
全内反射时由于表面波的存在,直接影响傅科棱镜出射偏振光的纯度。本文提出为了获得高纯度的偏振光,利用消光比的大小来选择空气层厚度的方法。
The existence of surface waves in total reflection directly a ffects the pureness of polarized light in Fou-cault Prism. This paper offers a way to achieve purer polarized light——by regulating the rate of light elimi-nation to determine the thickness of the gas layer..
