Abstract

Acoustic imaging may be useful in such applications as nondestructive testing, biomedical diagnosis, underwater viewing and micros copy. Unfortunately, however, the quality of images available from acoustic systems is not always satisfactory to human observers. A digital image-processing technique, employing minicomputers and relatively inexpensive input-output equipment, has been used for image enhancement and noise removal in images produced by a Bragg-diffraction system. This paper describes the technique and shows the results of applying the method in the case of a particularly simple image of a hook.
