In the article a brief description of the researches based on scientific ideas of academician F.I. Fedorov and executed in the field of research of optical activity of transparent and absorbing crystals in the Institute of Crystallography of the Russian Academy of Sciences is given. Results of study of polarizing characteristics of eigen waves uniaxial and biaxial crystals depending on the thickness of a crystal layer, temperature and other parameters are presented. In the article the information about devices and the methods of research developed and used in the Institute of Crystallography of the Russian Academy of Sciences for obtaining the information about optical properties of crystals (about components of gyration tensor, parameters of refraction, value of circular anisotropy, circular dichroism, etc., as optical active crystals, and not showing gyrotropy, in various phase conditions) is presented. The polarizing characteristics of the radiation passed through a crystal layer or reflected by it and calculated with the application of methods of computer modelling on the basis of the theoretical relations corresponding to variations of accuracy approximation are described. The article is added to the extensive list of the scientific works used for preparation of the manuscript.
