Recording dynamics of holographic gratings in polymer dispersed liquid crystals for thick layers has been investigated in this work. In contrast to existing theoretical models, besides the diffusion of monomer molecules, it have been taken into account the diffusion of polymer molecules. Our analysis shows that the profile of recorded diffraction grating becomes fuzzy when considering the diffusion processes of polymer molecules.
