The feasibility of utilizing acoustic imaging techniques for
improving the undersea viewing capability of small submersibles is
investigated. The limiting values of major parameters in acoustic
imaging systems are established and graphs which illustrate the
parametric relationships are presented. A series of sample calculations
illustrate how the graphs can be...
Acoustic scanned holography is a method of lensless photography
which uses sound waves to construct the hologram and light waves to
reconstruct the image. The receiving transducer scans a plane area
containing the sound field generated or scattered from the objects. In
simultaneous source receiver scanning, both the source and...
