Abstract

Development of a theoretical model of the processes present during the formation of a holographic grating in photopolymer material is crucial in enabling further development of holographic applications. To achieve this, it is necessary to understand the photochemical and photo-physical processes involved and to isolate their effects enabling them to be modelled accurately. Photopolymer materials are practical materials for use as holographic recording media, as they are inexpensive and self-processing. Understanding the recording mechanisms will allow their limitations for certain processes to be improved and a more efficient, environmentally stable material to be produced. In this paper we further develop our Non-local Polymer Driven Diffusion (NPDD) model to include the effects of absorption and inhibition effects. Thus we attempt to increase the accuracy of our existing model.
