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.
Highlights
The protein density of the albumin of quail egg is higher than that of hen egg [1] [2]
With the concentration suitable (AD) for the construction of optimal gratings with high diffraction efficiency (DE), these results demonstrate the ability of protein for storage holographic information, and with regard to types of proteins contained in the quail albumin; the ADPQA is more efficient
The results indicate the behavior of colloidal systems based on albumin bird, to build holographic recording materials
Summary
The protein density of the albumin of quail egg is higher than that of hen egg [1] [2]. The albumins were dehydrated in a container with silica gel to form crystal and the density was measured. This process was performed to obtain the percentage of water for each albumin. Photosensitive emulsion (ADPHA) was prepared using holographic recording analysis on films sensitized with ammonium dichromate (NH4)2Cr2O7(AD) [3]-[5], propylene glycol (P) [6]-[8] with hen albumin (HA). In addition to holographic recording analysis, the photosensitive emulsion (ADPQA) method was produced with quail albumin (QA). The photosensitive emulsions, ADPHA and ADPQA, were used the aqueous AD solution for obtaining the best optimization of high-quality photosensitive
