For this purpose, there was used a magneto-optical modulator, at the output of which the variable components of the Stokes vector have different initial phases. The advantage of the method is the absence of rotating optical elements, the independence of the measurement results with a change in the intensity in the optical circuit, which simplifies the measurement process. As an example, the results of measurements of magnetic linear birefringence in a film of yttrium garnet ferrite are given. The minimal increment of the phase shift between optical waves polarized along orthogonal linear polarizations （the Cotton-Mouton effect）, which was measured in this experiment is 0.01 deg.展开更多
