光可能具有光学角动量，这是一个已经知道并利用了一百多年的事实。起初，它完全与光的自旋角动量有关，通过光的偏振。最近，光的轨道角动量已经被研究并用于大量的应用。该分量与场的空间分布相关联。本文概述了自旋和轨道角动量的基本概念，它们通过矢量光束的连通性，以及光学角动量携带场的庞加莱球表示，并回顾了该领域的现状及其许多发展机会。保留字：光学角动量;轨道角动量;涡流束;矢量波束扭曲的光;光学光谱;高维量子纠缠
That light may possess optical angular momentum is a fact that has been known and exploited for over a hundred years. At first, it was entirely associated with the spin angular momentum of light, through light's polarization. More recently, the orbital angular momentum of light has been studied and exploited for a plethora of applications. This component is associated with the spatial profile of the field. This article outlines the basic concepts of spin and orbital angular momentum, their connectedness through vector beams, and Poincare sphere representations of optical angular momentum carrying fields and reviews the present state of the field and its many opportunities for advancement. Keywords: optical angular momentum; orbital angular momentum; vortex beams; vector beams; twisted light; optical spanners; high-dimensional quantum entanglement
