The hydrodynamics of surface layers of nematic liquid crystals studied by modulation ellipsometry

Abstract

An acoustically induced Poiseuille flow changes the director onentatlon of a nematic liquid crystal in a hybnd cell. Th1n surface layers (less than 0 2 ~L) m the vlcimty of solid interface are of special interest To study them we used a novel technique ofmodulation ellipsometry based on probing of the interface layers by an evanescent optical wave appeanng m a liquid crystal when light is totally reflected from the interface between the liquid crystal and heavy glass The essential details of the technique are the angle of light incidence is considerably higher than the total reflection angle and the a c acoustic excitation is used with a consequent lock-in detection of
