Scanning of the surface polar angle values in liquid crystal cells using the surface memory effect

An optical polarization method for indication of recorded oriented smectic C textures by the process of surface memorization and their accumulation an d storage in the nematic temperature range is presented. The recorded accum ulated data are identified with the surface conditions-the polar and azimut hal angles. Using strong boundary conditions the assumption is made that th e interval for recorded and accumulated textures increases when the anchori ng energy is weak.
