Study of the dynamic formation of transmission gratings recorded in photopolymers and holographic polymer-dispersed liquid crystals [PDF]
, 2004 Local and nonlocal models for the diffusion of photopolymers are applied to the dynamic formation of transmission gratings recorded in photopolymers and holographic polymer-dispersed liquid crystals (H-PDLCs). We retrieve the main parameters of H-PDLCs (
