Paper Abstract

After exposure and processing, the Cr6+ ion in dichromated gelatin (DCG) is reduced to Cr3+. The unexposed Cr6+ is washed out by water and , the gelatin cross linked with Cr3+. Since the density distribution of Cr3+ is proportional to the exposure of light, distribution of Cr3 will be sinusoidal. Meanwhile, the ions or molecules of other materials are distributed uniformly in a certain range around Cr3+. Therefore, the distributions of positive and negative charges will be unequal, and an electric field will be induced inside the medium of volume hologram in macro-scale. The intensity of such electric field is calculated basing on this mechanism. and it is found to be considerably strong.
