Real-Time Fourier Transformer Using One Acousto-Optical Cell.

Abstract

The field of the invention in general is an optical signal processor and in particular is an optical Fourier transformer utilizing one acousto-optical cell. Fourier transforms are used in many fields of technology for converting information from one representation to another. Fourier transformations of time-domain signals are particularly important in signal processing such as in the fields of radar and sonar for which the one-dimensional transformation is given.
