The diffusion equation is solved in the low-order harmonic approximation, in order to describe the grating formation process in dry photopolymer materials. We describe how the ratio between diffusion and polymerization rates controls the process of grating formation. Nonlinearity and reciprocity failure are predicted. Experimental results are also shown which are in qualitative agreement with the theory.read more

Nonlocal-response diffusion model of holographic recording in photopolymer
TL;DR: In this article, the standard one-dimensional diffusion equation is extended to include nonlocal temporal and spatial medium responses, and the resulting nonlocal diffusion equation was then solved numerically, in low-harmonic approximation, to describe grating formation.

Photopolymer holographic recording material
TL;DR: In this article, the authors proposed a non-local material response model that predicts that the spatial frequency response might be improved by decreasing the mean polymer chain lengths and/or by increasing the mobility of the molecules used in the material.

Quantitative model of volume hologram formation in photopolymers
TL;DR: In this article, Zhao and Mouroulis [J. Mod. Opt. 41, 1929] proposed a quantitative model to describe the formation of volume holograms in polymeric medium containing photopolymerizable acrylate monomers that undergo spatially modulated gelation as a result of exposure to a visible “write” beam.

Hologram recording in du Pont's new photopolymer materials
TL;DR: In this article, a new family of transmission and reflection holographic photopolymer materials and their performance are described. But their performance is limited to the application of holographic data recording, which consists of exposure, UV cure and heat processing.
