We present an analytical model of the dynamics of spatial harmonics of holographic grating profiles, taking into consideration record mechanisms (polymerization and components diffusion), absorption, interference pattern contrast and optional photopolymerization nonlinearity. On the basis of numerical simulation we compare the model presented with the non-local polymerization driven diffusion model. The results of fitting experimental data with the model results are also presented.
