“…Aging was observed with a variation in DE with regard to time of the already recorded holographic gratings. The capacity of films in relation to spatial frequencies by module transfer function (MTF) was determined [18]- [20] by varying the angle between the light beams to form gratings with different periods for both matrixes. All experimental results between the two albumins were compared.…”

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.
