基于瑞利散射的三维偏振度测量

A three-dimensional degree of polarization based on Rayleigh scattering

M. R. Dennis

摘要:

基于瑞利散射,提出了一种电磁场三维偏振矩阵(相干矩阵)偏振度的度量方法。由于三维偏振态的偶极散射,偏振度在所有散射方向上平均。这给出了一个定义明确的纯度测量,不同于其他提出的三维偏振度的测量,它不是矩阵的酉不变量。这是证明和讨论的几个例子,包括部分偏振的横向光束。

英文摘要:

A measure of the degree of polarization for the three-dimensional polarization matrix (coherence matrix) of an electromagnetic field is proposed, based on Rayleigh scattering. The degree of polarization, due to dipole scattering of the three-dimensional state of polarization, is averaged over all scattering directions. This gives a well-defined purity measure, which, unlike other proposed measures of the three-dimensional degree of polarization, is not a unitary invariant of the matrix. This is demonstrated and discussed for several examples, including a partially polarized transverse beam.
