Determination of Light-Induced Deformation Characteristics of the Director Field of Nematic Liquid Crystal by Combining the Methods of Aberrational Self-Action of Light Beam and Polarization Microscopy.

Light-induced director field deformation of a nematic liquid crystal in the field of an obliquely incident laser beam is experimentally studied with aberrational self-action and polarization microscopy. Each of the methods has features associated with the geometry of the light interaction with the director. The combination of methods significantly expands the possibilities of reconstructing the light-induced nonlinear phase shift profile and the director field deformation.
