Acoustically Scanned Image
Abstract
The report describes work on a new type of optical scanning device which makes use of acoustic surface waves to scan an optical image. The device employs a silicon semiconductor as the photodector; the nonlinear interaction of two acoustic surface waves, whose electric fields interact with the silicon is employed in the basic mechanism of detection. Work on the airgap Si-LiNbO3 convolver configuration which is employed in this optical imaging device is described. Described is the theoretical development of the semiconductor convolver theory. Development of the technology of the ZnO on Si convolver configuration for use in the optical imaging device is discussed. A short description is given of a chirp generator, which was constructed for use in transform coding in these types of devices.
