Abstract
Many applications of photorefractivity have been proposed, including a virtually unlimited array of image-processing techniques with phase conjugation and novelty filtering, simulations of neural networks and associative memories, and high-density efficient holographic optical storage, However, a crucial problem preventing the exploitation of the photorefractive effect is that the materials exhibiting the effect tend to be difficult and expensive to make and prepare.
