摘要
通过改变入射光的偏振特性和入射角度研究了菲涅耳效应对法拉第效应非互易性观测的影响.实验结果表明:含普通半透半反镜的光路中菲涅耳效应给偏振方向的准确观察带来误差,误差大小由反射界面折射率、入射角以及入射光偏振方向共同决定,结合实验结果,提出了非互易性验证实验的改进方案.
Fresnel effect yield by the non-reciprocity of Faraday effect was studied by changing the polarization and incident angle of the incident light.The experimental results showed that the Fresnel effect in optical path with half mirror caused errors in the observation of polarization direction.The magnitude of the error was determined by the refractive index,the incident angle and the polarization direction of the incident light.Combined with the experimental results,an improved scheme for the non-reciprocity verification experiment was proposed.
