Abstract
A multicomponent lattice Boltzmann model including external electric forces interactions is developed to study the behavior of a classical thermoplastic film which is used as a holographic recording material. The model incorporate also the spinodal decomposition originated in this type of polymeric fluids when a fast thermal pulse is used to develop the hologram. The surface deformation of the electrically charged thermoplastic film is simulated using the lattice Boltzmann model and the main holographic parameters, i.e., spatial frequency response (MTF) and diffraction efficiency are given and related to the hydrodynamic behavior of the fluid. The influence of the phase transition on the growth rate of the deformation and, hence, on the MTF response of the medium is studied and correlated with experimental results. The results obtained with our model are in agreement with those obtained using more complex theoretical analysis.
