Acoustically Scanned Optical Imaging Devices

Abstract

A storage correlator has been operated for the first time as an inverse filter by operating in a feedback loop to iteratively converge via the LMS algorithm to the desired filter. A pulse and a ghost echo have been deconvolved to a single pulse with the sidelobe level 9 dB below the original echo level. The ZnO magnetron sputtering system is operating well; ZnO on Si convolvers have been constructed with better efficiency (-55 dBm) than any we have previously made. A -45 dBm efficiency Delta(v)/v waveguide convolver has been constructed.
