摘要

A new method of determination of only an ellipticity of a state of polarization of a coherent radiation is proposed. The method is based on a spatial separation of a wave with the arbitrary ellipticity of a state of polarization into two waves with mutually orthogonal circular states of polarization. To part elliptically polarized light into two waves with orthogonal circular polarizations, the optical Magnus effect in a multimode optic fiber and a phase conjugator were used. The main advantage of a method is dealing with light intensities of almost the same values in the case of weekly elliptically polarized light. It was shown experimentally that precision of measuring increases noticeably for weakly elliptically polarized light. The simple device for the determination of the polarized light ellipticity is proposed.
