Holographic recording analysis was performed on the films that were sensitized with ammonium\ndichromate with albumin of hen and quail (Gallus gallus and Callipepla cali) as abiopolymeric\nphotosensitive matrix. The samples were exposed to an He-Cd laser, = 442 nm, at various concentrations,\nand diffraction efficiencies were measured as a function to the energy, thickness, protein\ndensity, aging time, and spatial frequencies. The photosensitivity was measured as a function\nof storage time, and the gratings were recorded in real time. The photochemical processes involved\nin the formation of holographic image are described. The results indicate the behavior of\ncolloidal systems based on albumin bird build holographic recording materials.
