We propose a polarimetric method for measuring the tilt angle of the LC director at an LC layer interface.The method involves the use of an LC cell operating in the mode of the total internal reflection of the ordinary wave. The method is based on me

The refraction of light, i.e., the turn of an extraordinary ray in the liquid crystal layer similar to total internal reflection at an interface between two media, has been studied in a cell with the homeoplanar orientation of the director. The rise,
