Acoustically Scanned Optical Imaging Devices

Abstract

A number of new ZnO based monolithic acoustoelectric devices have been demonstrated during the past three years, including Sezawa wave convolvers and storage correlators with 36 MHz bandwidth, Rayleigh wave Schottky diode and p-n diode storage correlators, and GaAs convolvers operating in a nonlinear resistive mode. These devices have been demonstrated in chirp and PSK compression experiments. A new, extremely fast SAW based adaptive filter was demonstrated in a variety of experiments, including echo suppression, spurious signal suppression, and impulse response improvement of a bulk wave transducer. A reactive magnetron sputtering system was constructed, and the optimum deposition parameters were determined. ZnO films were deposited at extremely high rates (10 - 20 microns/hour), and excellent orientation is routinely obtained (FWHM of (0002) peak 5.3 deg).
