随机偏振光场的三维结构以其偏振奇点为例：沿其偏振为纯圆形的线（C线）和沿其偏振为线性的面（L面）。我们在矢量激光散斑场和随机波叠加的数值模拟实验中可视化了这些偏振奇点。我们的结果证实了先前的分析预测[M]。R. Dennis, Opt. common . 213, 201(2002)]关于C点类型的统计分布及其二维属性与三维结构的关系。
The 3D structure of randomly polarized light fields is exemplified by its polarization singularities: lines along which the polarization is purely circular (C lines) and surfaces on which the polarization is linear (L surfaces). We visualize these polarization singularities experimentally in vector laser speckle fields, and in numerical simulations of random wave superpositions. Our results confirm previous analytical predictions [M. R. Dennis, Opt. Commun. 213, 201 (2002)] regarding the statistical distribution of types of C points and relate their 2D properties to their 3D structure.
