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.
Claims26
In an optical recording system, the improvement comprising at least two photorefractive crystallytes, wherein said crystallytes are capable of being selectively addressed for optical holographic recording, storage and reconstruction.
In a signal processing system, the improvement comprising at least two photorefractive crystallytes, wherein said crystallytes are capable of being selectively addressed for optical signal processing.
An optical array comprising at least two photorefractive crystallytes capable of being selectively addressed for at least one of optical signal processing or halographic recording.
A method for selectively processing an optical signal, comprising providing at least a plurality of photorefractive elements for recording at least certain spatial frequency components of an associated optical image;
- and selectively activating said elements to enhance or diminish said associated spatial frequency components.
