Coherency matrix polarization measurements: application to magnetooptic garnet films.
A method of completely determining the polarization of light is described. An algorithm that allows a fast numerical evaluation of the coherency matrix based on the results of four nonequivalent polarization measurements is presented. The method has been applied to determine the degree of polarization, ellipticity, and orientation of the major axis of light transmitted through a magnetooptic thin film on a garnet substrate as a function of magnetic field. Representative results are given.
