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.

Book 1972ctivity in the field. More than 500 papers and articles on holo graphy have appeared in the last ten years. 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
