Chirality is exhibited by objects that cannot be rotated into their mirror images. It is far from obvious that this has anything to do with the angular momentum of light, which owes its existence to rotational symmetries. There is nevertheless a subtle connection between chirality and the angular momentum of light. We demonstrate this connection and, in particular, its significance in the context of chiral light-matter interactions.This article is part of the themed issue 'Optical orbital angular momentum'.
手性由无法旋转成自身镜像的物体表现出来。这与光的角动量有何关联远非显而易见，而光的存在归因于旋转对称性。然而，手性与光的角动量之间存在着微妙的联系。我们展示了这种联系，特别是其在手性光与物质相互作用背景下的重要性。本文是“光学轨道角动量”主题特刊的一部分。
