Information About Author:

New demonstrations on conical refraction in a monocrystal of rhombic sulfur are presented. Double ring 1 m diameter of internal conical refraction was shown on a screen of auditorium. Two rings of external conical refraction with specific distribution of polarization have been obtained and there was shown the ring of external refraction does not display any double structure. Focusing features of a parallel-plane slab of biaxial crystal have been sexperimentally evaluated. New definitions of birefringence in conditions of conical refraction are discussion
