Abstract
A photorefractive crystallyte array for image recording and signal processing is disclosed. The photorefractive crystallytes are configured as a two-dimensional array of selected position and spacing designed, for example, to coincide with the spatial frequency components of an associated optical image, such as a Fourier transform image, and to permit optical signal processing.
