摘要

In the last years many diffusion models have been proposed to explain the hologram formation in photopolymers. This material has a lot of attractive features as self-developing, high storage capacity (ease process to obtain thick dry layers), high diffractions efficiencies etc. In this work the availability of a first harmonic diffusion model proposed by C. Neipp et al. to describe the recording process for different visibilities is demonstrated. The problems to achieve high diffraction efficiencies at low spatial frequencies for PVA/acrylamide based photopolymer are also solved, and a possible description of this phenomenon is obtained using the diffusion model proposed.
