摘要
光子轨道角动量具有涡旋和高维特性,在经典和量子领域有巨大应用潜力,目前在光学系统中有多种轨道角动量识别方法,常见的方法有以下8种:干涉仪法、镜像干涉法、平面波干涉法、角双缝干涉法、三角孔衍射法、计算全息光栅法、光学几何变换法和旋转多普勒效应法.本文详细介绍了8种方法的实验原理、实验装置、实验结果及现阶段的研究成果.
The orbital angular momentum of photons characterizes both high dimensions and optical vortices and shows a great of potential applications in quantum and classical fields.At present,the mostly used eight methods for identifying orbital angular momentum in optical systems are:interferometer method,mirror interferometry,plane wave interferometry,angular double-slit interferometry,triangular aperture diffraction,computational holographic grating method,optical geometric transformation method and rotational Doppler effect.This paper introduced in detail the experimental principle,experimental setup,experimental results and current research status of the eight methods.
