Abstract: Analytical models of light diffraction by multiplexed chirped multilayer individual holographic diffractive structures formed in photopolymer composite materials containing nematic liquid crystals, as well as in polymer dispersed liquid crystal materials, are presented. Particular attention is paid to structures with smooth optical inhomogeneity in holographic gratings, including photopolymer materials with liquid crystals, as well as structures formed exclusively in dispersed liquid crystals.

Keywords: photopolymer materials, liquid crystals, multilayer diffraction structures, chirped, multiplexed.
