A study of fast mechanical scanning for acoustical holography

posted on 2018-10-25, 10:59 authored by Michel J.-M. ClementAcoustical holography provides a technique with many current and
potential uses. However, a convenient area detector equivalent to the
photographic plate is not available for acoustical waves; this has initiated much research and a wide variety of recording techniques have
been developed. Most of these methods, however, suffer either from lack
of sensitivity, or a prohibitively small recording area. One way to combine
good sensitivity without potential aperture limitation, is to scan the area with a sensitive receiver.
Scanning techniques offer great versatility, such as range gating,
source scanning, electronic reference simulation, imaging of large or
thick objects, signal processing and insonification by reflection.
Such a method, however, introduces an undesired scanning time which is
troublesome in most applications. [Continues].
