Liquid-Surface Holography, the wave front should be either spherical or plane. This sound beam will be referred to as the reference beam. The other beam, referred to as the object beam, must be essentially coherent * with the reference beam and should insonify the object uniformly but may have any wave front geometry.

取之不竭

Book 1972esults of research in acoustical holography, some of it as yet unpublished, under one cover so that workers in holography, nondestructive testing, medical imaging, underwater imaging, and seismic exploration can decide whether this new technique can be useful to them.

Many applications of holo­ graphy have been proposed, and some of these are beginning to enter the realm of usefulness. One of the applications that appears to hold great promise is acoustic
