Abstract
In this work the numerical simulations of the holographic formation of diffractive optical elements for the light beams conversion into Bessel-like ones in polymer-dispersed liquid crystals (PDLCs) are performed. Theoretical model for simulations is based on the solution of the kinetic equations of photopolymerization-diffusion processes of holograms recording in PDLCs by light beams with inhomogeneous amplitude and phase spatial distributions. Kinetics of spatial harmonics of refraction index changings are investigated and it is shown that during the recording process the spatial profile of diffractive optical element is changing from sinusoidal to inharmonic one. This process is also depends on the ratio of the diffusion and photopolymerization processes rates.
