The spatial dispersion in inhomogeneous media is studied, that gives rise to optical gyration of a new type. The approach for describing multiple reflections in crystals is developed. The optical techniques for studying domain structure of ferroics are applied. The influence of dichroism on the gyration and characteristics of optical filters is studied. The imaging polarimeter is applied to the problem of measuring optical activity. Product Description popup.authors popup.nrat_date 2020-04-02 Close
