Holographic Optical Element Materials Research.

Abstract

An experimental program was conducted to study and improve the achievable holographic index modulation in dichromated gelatin suitable for producing high-quality holographic optical elements. Emphasis was placed on gaining a working knowledge of the chemical and physical processes involved in dichromated gelatin image production. The largest improvement in index modulation was achieved with the application of dicarboxylic acid salts. Index modulation could be increased by up to 150% per unit of light exposure over conventional processing methods by taking advantage of unipointly attached reduced chromium complexes. We confirmed the usefulness of the sol temperature as a measure of bulk cross-linking in gelatin. With polycarboxylic acids, index modulations of 0.16 were obtained in reflection holograms.
