论文摘要
本教程概述了非帕型光的极化的局部描述，对此，电场的所有笛卡尔组件都很重要。每个点的光的极化为特征是在完全极化的情况下，或$ 3 \ times3 $偏振矩阵用于部分极化。近端极化的标准概念，例如极化程度，Stokes参数和Poincaré球，然后对非独特或不是琐碎的非携带光具有概括性。这项工作旨在澄清其中一些差异，提出一些新概念，并提供一个框架，以突出与近距离制度的描述相似之处和差异。特别强调几何解释。
This tutorial provides an overview of the local description of polarization for nonparaxial light, for which all Cartesian components of the electric field are significant. The polarization of light at each point is characterized by a $3$ component vector in the case of full polarization or by a $3\times3$ polarization matrix for partial polarization. Standard concepts for paraxial polarization like the degree of polarization, the Stokes parameters and the Poincaré sphere then have generalizations for nonparaxial light that are either not unique or not trivial. This work aims to clarify some of these discrepancies, present some new concepts, and provide a framework that highlights the similarities and differences with the description for the paraxial regimes. Particular emphasis is placed on geometric interpretations.
