Optical Computing

Abstract

The advantage of optical computing is its parallelism. In the case of photography, every part of an object is focused by a camera lens onto a film to construct an image of the object. This image forming process constitutes the basis of optical parallel processing and optical computing is a technology that transforms the concept of optical processing into various information processing techniques. Various research has been conducted in the field of optical information processing to develop retrievable optical memories using the lens as the means to perform Fourier transformations or the holograms, but non of the methods has been put into practical use. They utilize the devices in classical optics such as the lenses to perform basically different functions from electronic devices.
