根据光在格兰泰勒棱镜和格兰傅科棱镜空气隙胶合层中的干涉效应,分析了空气隙偏光棱镜对单模高斯光束光强分布的影响;结果表明:对于某一波长的入射光,当空气隙的厚度一定时,透射光强随光在空气隙介面上入射角的变化作周期性振荡;当入射角一定时,透射光强随空气隙厚度的变化作周期性变化;且透射高斯光束的形状也随光的入射角以及空气隙厚度的改变发生变化;且无论是透射光强的周期性振荡,还是透射高斯光束的形状的变化,格兰泰勒棱镜的影响均小于格兰傅科棱镜;这说明前者的综合性能优于后者。

研究发现：(1)薄膜外加垂直磁场时,光透射强度随着磁场强度的增加而减小；(2)薄膜外加平行磁场时,垂直偏振光和平行偏振光的透射强度随着磁场强度的增加而变化规律不同； (3)存在一个临界磁场,其值约为4776A/m,当外加磁场(垂直和平行)强度＞4776A/m 后,薄膜透射光强的变化规律有明显不同,这种现象是由于外加磁场使纳米磁性液体微粒产生聚集,磁场＞4776A/m 后,形成有规则的排列结构所造成；(4)纳米磁性液体外加垂直磁场下透射强度的响应时间随磁场强度的变化情况。
