Researches concerned with selective properties and processes of formation of nonuniform and nonstationary Bragg holograms in various recording materials are reviewed. Volume hologram models regarding the nonuniform light absorption, the recording layer thickness shrinkage, the change in the modulation value and the average refractive index value through the hologram depth, and showing the difference between selective properties of such holograms from the ideal knowledge are described. Analytical and numerical research methods that are most suitable for each model are considered.
