Resolution improvement in acoustic holography using aperture expansion techniques

One of the main reasons for the restricted application of holography in acoustic imaging is the limited resolution due to the relatively small numerical aperture for a given physical aperture. There is also a lack of suitable acoustic area detectors which provide adequate sensitivity and spatial res...
