Recent advances in new holographic silver halide materials

Photographic emulsions are still one of the most widely used recording materials, due to the high energetic and spectral sensitivity and ease of processing. In order to obtain holograms of high quality on photographic emulsions, the different chemical procedures applied to the emulsions must be optimized. In this work we study two particular procedures, silver halide sensitized gelatin and fixation-free rehalogenating bleaching applied to two new commercial silver halide emulsions: the BB-640 plates from Holographic Recording Technologies and Slavich PFG-01 plates.This study was supported by the CICYT of Spain under projects MAT97-0705-C02-02 and MAT2000-1361-Co4-04
