Abstract

A new two-dimensional DEFT sensor (for Direct Electronic Fourier Transform) for multi-processing will be described. Operating at a center frequency of 100 MHz, it is capable of resolving 1800 unique spatial Fourier image components in a random access mode. As a Fourier transformer it can identify vector spatial frecuencies, their amplitude and phase. By suitable change of input functions, the device can be operated as a spatial raster scanner, Hadamard transformer, matrix multiplier, or convolver. The device achieves this flexibility by virtue of producing the spatial integral of the product of two electronic signals with an optical signal.
