基于费马原理，建立了单轴晶体中非常光线(e光线)折射和反射的普适理论。利用这一理论，设计了一种新的单元结构棱镜，并对其性能进行了研究。在理论分析的基础上，利用冰洲石晶体实现了这种棱镜。在理论和实验研究中，这种新型棱镜与传统的罗洪棱镜相比，具有分束角大、可调等优良的偏振分束性能。对于光轴角度为45°的样品棱镜，垂直入射时的分束角达到19.8°，入射角度为-4°时，最大分束角达到28.44°。
Based on the Fermat's principle, the universal theory of refraction and reflection of extraordinary rays (e-rays) in the uniaxial crystal is formulated. Using this theory, a new unit structure prism is designed, and its properties are studied. Based on the theoretical results, such a prism is achieved experimentally by using the Iceland crystal. In both theoretical and experimental studies, this new prism shows excellent polarization splitting performances such as big and adjustable splitting angle, comparing to the conventional Rochon prism. For the sample prism with the optical axis angle of 45°, the splitting angle reaches 19.8°in the normal incidence, and the maximum splitting angle reaches 28.44° while the incidence angle is -4°.
