Effects of absorption and inhibition during grating formation in photopolymer materials
, 2006 Photopolymer materials are practical materials for use as holographic recording media, as they are inexpensive and self-processing (dry processed). Understanding the photochemical mechanisms present during recording in these materials is crucial to ...

New Materials by Photopolymerization
CHIMIA, 1993 Despite lateral resolution being the most intensely studied topic in photopolymer research, vertical resolution properties finally add the decisive momentum to reach the desired performance in photopolymer layers. We will describe four different

Adjusted intensity nonlocal diffusion model of photopolymer grating formation
, 2002 Diffusion-based models of grating formation in photopolymers have been proposed in which the rate of monomer polymerization (removal) is directly proportional to the illuminating intensity inside the medium. However, based on photochemical considerations,

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 (
