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