Space/Frequency Conversions in Image Processing and Transmission.

Abstract

This research program centers on the investigation of a new optical/electronic method for highspeed convolution and correlation of two-dimensional imagery. The method, based on frequency-division multiplexing of image samples, is suited to implementation with wideband acoustooptic devices. During the report period the following has been accomplished: Development of a time-integration method for obtaining image output, Development of methods for production of improved encoding/decoding local oscillator distributions, Development of a general Fourier transform scanning hybrid image processor concept, Development of important analogies between space-frequency conversion image processing, time-integration folded spectrum analysis, and Fourier transform holography, and Development of a joint-transform method for space-frequency conversion image processing. These developments enhance greatly the prospects that the space-frequency conversion scheme can be satisfactorily implemented in a wideband image processing system.
