Non-local material response of photopolymer holographic materials

The non-local model assumes that monomer molecules are polymerised to form polymer chains and that these chains are not constrained-to the illuminated regions, i.e. they are non-local. A non-local response function was added to account for this non-local effect. In this paper the-generalised model previously published by the authors was further extended to allow for non-linear proportionality to the recording illumination. The resulting equations are presented in this paper. The two harmonic analytic formulae for this extended generalised response function model are also presented in this paper.
