Acoustically Scanned Optical Imaging Devices

Abstract

Results obtained with the airgap convolver system are described. It is shown that the system is very suitable for use in a storage correlator; the basic problems are associated with bulk wave feedthrough and other spurious responses. Considerable progress has been made in this respect. The experimental results we have obtained, and a detailed theory of the device which we have developed, tend to indicate a possible dynamic range for the device of 60 dB, well comparable to the convolver. The device is ideally suitable as a variable delay device, which can be externally programmed to delay signals several hundred microseconds long by times of a few microseconds.
