摘要
为了实现法拉第磁光角的直接观测,设计了一个基于纳米径向偏振光栅的法拉第磁光角测量系统。介绍了法拉第磁光角测量系统的检测原理、光路设计以及操作步骤,并搭建了仿真和实验平台对系统的可行性进行验证。结果表明,该系统不仅能够实现0°~360°法拉第磁光角的测量,还能够呈现磁场作用下法拉第磁光角的动态变化过程。该系统有助于学生掌握法拉第磁光角与磁场的直接关系,加深对法拉第效应的理解与认识。
In order to realize the direct observation of the Faraday magnetic angle,a Faraday magneto-optical angle measurement system based on nanometer radial polarization grating is designed.The detection principle,optical circuit design and operation steps of the Faraday magneto-optical angle measurement system is presented.A simulation and experimental platform is established to verify the feasibility of the system.The results show that the proposed system not only realizes the 0°~360°Faraday magneto-optical angle measurement,but also shows the dynamic change process of Faraday magneto-optical angle under the action of magnetic field,which can help students master the direct relationship between the Faraday magneto-optical angle and magnetic field,and deepen the understanding of Faraday effect.The experimental measurement system integrates electricity,optics and nanomaterials,which is conducive to students for frontier scientific experimental technology and concepts.
