Acoustical Holography, Softcover reprint of the original 1st ed. 1971
Volume 3 Proceedings of the Third International Symposium on Acoustical Holography, held at the Newporter Inn, Newport Beach, California, July 29–31, 1970

This volume presents the proceedings of the Third International Symposium on Acoustical Holography, which was held at the Newporter Inn, Newport Beach, on 29-31 July 1970. The symposium was sponsored by the Douglas Advanced Research Laboratories, McDonnell Douglas Corporation, and the Acoustical Society of America. Twenty papers were presented and these each appear as a chapter in this volume. The chapters are grouped into five sections. The sections are I Medical and Biolog­ ical, II Bragg Imaging, III Nondestructive Testing, IV Underwater and Long Wavelength, and V Theory and Methods. The reader is cautioned only to use the sec­ tional titles as a rough guide. For instance, the reader interested in new methods should not just read section V since he will find a new liquid surface relief method de­ scribed in chapter lOin section III. In an effort to reduce the time delay between the meeting and the publication date, the publishers have pro­ duced this volume using the shoot-from-manuscript method instead of the mote time consuming typesetting method that was used on the previous volumes. As a result there may be differences in notation and definitions used for one chapter to another. However this should not cause con­ fusion since all symbols and definitions are stated in each chapter. The editor wishes to thank the session chairmen, Dr. Vincent Salmon, Stanford Research Institute; Dr. Isadore Rudnick, University of California at Los Angeles; Dr. Lewis Larmore, McDonnell Douglas Corporation; Dr.
