This paper presents a research of the process of holographic formation of chirped multilayer inhomogeneous holographic diffraction structures in polymer encapsulated liquid crystals under conditions of linear and nonlinear recording modes. In the course of investigation it was found that under different modes of recording, lattice profiles could have two-dimensional inhomogeneity and differ from layer to layer, which was caused both by the influence of material absorption and change of period of holographic diffraction structure.
