Abstract
We propose a partial differential equations model for the formation and evolution of a holographic grating in a photopolymer system and use perturbation methods and numerical simulations in order to investigate the dynamical mechanism by which distortions of the illumination pattern arise during recording. The parameters of interest are diffusion and photopolymerization rates as well as exposure time, for which we seek to determine regimes which allow for high fidelity copying.
