Acoustical Holography, Scanning Techniques

Conference paper


One major impediment to the development of optical holography from the time of its inception by Gabor (1) to the time of renewed interest generated by Leith and Upatnieks (2) was the lack of sufficiently coherent and intense sources of light. No such limitation impeded the development of acoustical holography. Coherent transmitters of acoustical waves at all frequencies have been available for many years. It is necessary, however, to devise a substitute for the square law area detector used in optical holography, since photographic plates are of only marginal use in recording acoustical holograms (3). A variety of substitutes have been demonstrated to be effective (4–8).
