Holographic interconnectors in silver halide sensitized gelatin

Abstract

When making interconnection holographic systems, it is important to obtain high diffraction efficiency and low noise levels. Silver halide sensitized gelatins have been shown to be an excellent material to use in transmission holographic systems because these two objetives can be met. Using a copying process that has been throughly tested in our laboratory, we obtained a 64-beam interconnector with a diffraction efficiency of 12.3% and a signal to noise ratio of 8.5 in each beam. The deviation between the diffraction efficiency of each diffracted beam is 58%. A improvement over the values corresponding to the original that was used in the copying process is achieved.
