1·In 1808, Malus discovered the polarized phenomenon of light. From then on, polarization optics became a important subject of optics.
1808年马吕斯发现了光的偏振现象，从此偏振光学成为光学学科的一个重要分支。
2·Based on characteristics of optical polarizing, Malus law, and Faraday optical rotation, a long-range displacement detector is realized by same light source and double light route.
基于光的偏振特性、马吕斯定理和法拉第旋光效应，采用同光源双光路检测，实现了大量程直线位移的测量。
3·As an example, Malus law 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。
4·It is found that the variation of the transmitted intensity with the rotation Angle deviates from Malus law, 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。
