Paper Abstract

Hypothesis of formation changes on image through photo-physicochemical processes is proposed. For record the holographic grating: [albumin + water + iron ammonium citrate + hv], the photo-crosslinking through transfer of electrons due to ions mobility and radicals in the system. Polarity by charge transfer and the formation of free radicals among atoms and molecules occurs with application of laser He-Cd, λ = 442nm. Photochemical reactions, produces intramolecular bonds. The holographic gratings thickness were 80μm, with diffraction efficiency of 15%.
