摘要
本文探讨了可调双折射滤光器中确定晶体等元件晶轴排列方向的几个普遍规律。利用这些规律,几乎不用任何数学推导,就可简单、准确地确定双折射晶体、波片及调节波长用旋转波片方向之间的关系。
This paper discusses several principles of determination of the crystal elements' orientation arrangement in adjustable-wavelength birefringent filters. By using these principles, we-are able to determine the relations of the orientations among the birefringent crystal plates, the waveplates and the rotated 1/2 waveplates simply, clearly and accurately without any complicated mathematical calculations.
