Analysis of dynamics of holographic grating formation with inharmonic spatial distribution in photopolymer + liquid crystal compounds

摘要

We present an analytical model of dynamics of three spatial harmonics of 2D spatial grating profiles with taking into consideration both record mechanisms (polymerization and components diffusion), absorption, interference pattern contrast. On the base of numerical simulation we examined an influence of these parameters on 2D spatial profile along grating vector and along thickness of a film.
