Abstract :
In this work we present the analytical model of light beam diffraction on holographic recorded polymer-dispersed liquid crystals anisotropic gratings controlled by an electrical field and their diffraction properties investigation. Optical anisotropy, statistics of LC orientation distribution in the droplet, optical nonuniformity of PDLC layer caused by reorientation of the mean values of principal axes of liquid crystal droplets in the homogeneous electrical field, photopolymeric and liquid crystalline components of diffraction structures are taken into consideration.
