Electro-Optical Response of Cells with Homeoplanar Layers of a Nematic Liquid Crystal with Different Thicknesses at Oblique Incidence of Light

摘要

Electrically controlled light refraction in a nematic liquid crystal (LC) with homeoplanar orientation possessing different thicknesses has been investigated at angles of light incidence on the layers exceeding the angle of total internal reflection of an ordinary beam delta(o). The optical response rise and decay time dependences (tau(on) and tau(off), respectively) on the electric field and angle of light incidence delta on the LC layer are obtained for LC cells with thicknesses d = 7, 14, and 22 mu m.
