Abstract
We study the effect of the hypersensitization with sodium sulphite in Agfa-Gevaert 8E75HD holographic plates in reflection holograms. An enhancement of energetic sensitivity and diffraction efficiency is observed with low solvent effects when Agfa-Gevaert 8E75HD are pre-processed. A 2–5 times increase of the sensitivity, together with temporal stability, is observed in reflection holograms.
