Abstract

Experimental investigation of acoustic and optical properties of thin homeotropic layers of nematic liquid crystals under the influence of a low-frequency periodic shift has been carried out. The cell under study was a «sandwich» with a moving symmetrical plate in the centre. It was found that the relaxation processes of the director reorientation after disabling the perturbation are described by exponential time dependence; the relaxation times are tens of seconds.

Keywords

nematic liquid crystal, relaxation of liquid crystals.
