摘要
光的偏振和轨道角动量特性在光学科学技术中具有重要的意义,特别是在高精度光学测量和高容量光通信等领域.本实验展示了一种高精度光学测量电压的方法,该方法通过塞格纳克干涉仪使偏振相互垂直的两束光携带轨道角动量(OAM),并与双折射晶体组合,利用干涉效应得到了一个携带OAM光束的"扇形"光学旋转器.该实验将抽象的物理理论知识应用到具体实践中,有助于提高学生的科研兴趣,激发学生的创新思维.
Abstract
The polarization and orbital angular momentum properties of light are of great significance in optical science and technology,especially in the fields of high-precision optical measurement and high-capacity optical communication.In this experiment,we demonstrate a high-precision optical voltage measurement method that uses a Sagnac interferometer to make two beams of light with polarization perpendicular to each other carry orbital angular momentum(OAM),and combine them with birefringent crystals to obtain a"fan-shaped"optical rotator carrying OAM beams by using the interference effect.This experiment applies abstract physical theoretical knowledge to concrete practice,which helps to improve students'interest in scientific research and stimulate students'innovative thinking.
