Abstract

There are lots of ions Cr³⁺ in dichromated gelatin (DCG) after exposure and processing. 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.
