Abstract
An optical image is converted into an electrical signal by utilizing acoustic surface wave convolution in a monolithic structure composed of a piezoelectric zinc oxide film on a silicon substrate. Measurements are presented describing the variation of convolution efficiency with light intensity, input acoustic power, and convolver gate electrode dc bias. An initialization procedure is described that allows the device to operate either in an image memory mode or in a nonstorage mode which permits scanning of nonstationary images.Keywords
