三维偏振态的二阶表征可以由相应的三维相干矩阵或相关的三维斯托克斯参数提供。通过对实验室参考系正交变换下不变的偏振特性的分析，可以定义一组六个本征斯托克斯参数，从而从有意义的物理特性方面简化解释偏振的三维状态。以一致的方式直接检索二维偏振态的旋转不变性，使二维本征Stokes参数由强度、线偏振度和圆偏振度组成。
The second-order characterization of a three-dimensional (3D) state of polarization is provided either by the corresponding 3D coherency matrix or (equivalently) by the associated 3D Stokes parameters. The analysis of the polarization properties that are invariant under orthogonal transformations of the laboratory reference frame allows to define a set of six intrinsic Stokes parameters which provides a simplified interpretation of 3D states of polarization in terms of meaningful physical properties. The rotationally invariant properties of 2D states of polarization are straightforwardly retrieved in a consistent way, so that the 2D intrinsic Stokes parameters are constituted by the intensity, the degree of linear polarization and the degree of circular polarization.
