A Table of Some Coherency Matrices, Coherency Matrix Factors, and Their Respective Mueller Matrices

Photonics, 2022
Many books on polarization give tables of Mueller matrices. The coherency matrix has been found useful for interpretetion of the Mueller matrix. Here we give a table of Mueller matrices M, coherency matrices C, and coherency matrix factors F for ...
