As an example, Maluslaw is proved experimentally with this instrument and its double bcams system.
作为实例，用本仪器搭置了双光路系统，验证了马吕斯定律。

It is found that the variation of the transmitted intensity with the rotation Angle deviates from Maluslaw, exhibiting a cyclic fluctuation with the rotation Angle.
实验中发现，透射光强曲线随着入射角的微小变化而偏离马吕斯定律，出现了周期性扰动。

Based on characteristics of optical polarizing, Maluslaw, and Faraday optical rotation, a long-range displacement detector is realized by same light source and double light route.
