Influence of the Molecular Weight Distribution of Gelatin on the Image Quality of Dichromated Gelatin Phase Holograms

摘要

Gelatins with differing molecular weight distributions were prepared by a water jet method. Dichromated gelatin (DCG) plates were then prepared with these different molecular weight distributions. It was clear that the difference in the molecular weight distribution of gelatin influenced the diffraction efficiency and SN ratio of a DCG hologram.
