Paper Abstract

Photo-physicochemical processes involved in the images recording are described. A holographic grating in recording process generates photo-crosslinking through electron transfer, by the active and not active radical mobility ions in the system [PVA + FeCl3 + H2O + hv]. The electric charges reorientation by the polarity between atoms and molecules establish intramolecular crosslinks. This process is essential due to the photochemical reaction for reducing Fe3+ to Fe2+ ion. The optimal holographic film shows diffraction efficiency the order of 26%.
