ABSTRACT
A special nontraditional optical geometry with a pure twist deformation induced by a homogeneous “in-plane” electric field in the layer of nematic liquid crystal (LC) is presented. A quantitative agreement of the theoretical and experimental results of the measured LC birefringence is obtained. A method for measuring the twist elastic module K22 and the rotational viscosity coefficient γ1 of nematic LC is proposed.
