Book Description
Since the first papers by E. N. Leith and J. Upatnieks on the subject of holography appeared in 1961, there has been a virtual explosion of research activity 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 imaging by means of holography. The first papers on this subject appeared in 1966, but already research activity in the field is burgeoning. Three symposia wholly devoted to acoustical holography have been held and the papers published in book form. The purposeof this book is to bring together the results of research in acoustical holography, some of it as yet unpublished, under one cover so that workers in holography, nondestructive testing, medical imaging, underwater imaging, and seismic exploration can decide whether this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.

Book Description
This volume presents the proceedings of the Second International Sym posium on Acoustical Holography, which was held at the Douglas Advanced Research Laboratories on 6 and 7 March 1969, fifteen months after the first symposium. Space was limited to about 110 seats, with representatives from nine countries attending. These countries included Canada, England, France, Japan, Mexico, Scotland, Sweden, Switzerland, and the United States. The symposium consisted of 21 formal papers. The twenty second, by Dr. U. Fehr, was not read, but is included in these proceedings. The manu script of the interesting paper on acoustic propagation in a turbulent medium which was read by Dr. O. K. Mawardi was not received in time for publication in these proceedings, and we look forward to its publication perhaps at a later date in the open literature. In addition to the formal papers there were three informal presentations at the end of the meeting which were given by Dr. A. Lohmann, by L. A. Cram and K. O. Rossiter, and by T. S. Graham, which are also included in these proceedings. At the end of the formal presentations Dr. Lewis Larmore summarized the symposium and discussed some of the highlights. For the symposium summary and a summary of these proceedings the reader is referred to Chapter 1.

Book Description
This volume contains the Proceedings of the Fifth International Symposium on Acoustical Holograhy and Imaging, held in Palo Alto, California, on July 18-20, 1973. The title of this Symposium differed from that of the previous four by the addition of the word "Imaging," reflecting an increase in emphasis on nonholographic methods of acoustical visualization. For convenience, no change has been made in the title of this published series. The 42 Symposium papers cover a wide range of theoreti cal and applied topics, and effectively define the state-of the-art in this rapidly developing field. Many of them relate to applications of acoustic visualization in such diverse fields as nondestructive testing, medical diagnosis, microscopy, underwater viewing, and seismic mapping. The papers presented at the Symposium were selected with considerable assistance from the Program Committee. The Editor wishes to thank the following persons for serving as members of this committee: P. Alais, University of Paris, France; B. A. Auld, Stanford University; D. R. Holbrooke, Children's Hospital of San Francisco; A. Korpel, Zenith Radio Corporation; J. L. Kreuzer, Perkin Elmer Corporation; A. F. Metherell, Actron Industries, Inc.; R. K. Mueller, Bendix Research Laboratories; B. Saltzer, u.S. Naval Under sea Research and Development Center; F. L. Thurstone, Duke University; and G. Wade, University of California, Santa Barbara.

Book Description
Fourier Acoustics develops the theory of sound radiation completely from the viewpoint of Fourier analysis. This powerful perspective of sound radiation provides the reader with a comprehensive and practical understanding which will enable him or her to diagnose and solve sound and vibration problems of the 21st century. As a result of this perspective, Fourier Acoustics is able to present thoroughly and simply, for the first time in book form, the theory of nearfield acoustical holography, an important technique which has revolutionized the measurement of sound. The book includes: The physics of wave propagation and sound radiation in homogeneous media Acoustics, such as radiation of sound, and radiation from vibrating surfaces Inverse problems, for example the thorough development of the theory of nearfield acoustical holography Mathematics of specialized functions, such as spherical harmonics The author is an internationally recognized acoustician whose pioneering research in the field of nearfield acoustical holography has impacted acoustics research and development throughout the world. Dr. Williams' research has been formally recognized by NRL as one of its most innovative technologies over the past 75 years. Relying little on material outside the book, Fourier Acoustics will be invaluable as a graduate level text as well as a reference for researchers in academia and industry. The book is unique amongst acoustics texts, it is well illustrated and it includes exercises to enforce the theory.

Book Description
This volume contains the Proceedings of the Sixth International Symposium on Acoustical Holography and Imaging, held in San Diego, California, February 4-7, 1975. The title of this symposium differs from that of the first four by the addition of the word "Imaging", reflecting an increase in emphasis on nonholographic methods of acoustical visualization. For convenience, no change has been made in the title of this published series. The 38 papers presented here define the state-of-the-art in the rapidly developing field of acoustical holography and imaging. Many of them describe applications in such fields as medical diagnostics, microscopy, nondestructive testing, underwater viewing, and seismology. The Editor recognizes the diligent efforts of the authors in advancing the technology of Acoustical Imaging and thanks them for preparing and submitting descriptions of their work. The papers were selected with the able assistance of the Program Committee that con sisted of P.S. Green, Stanford Research Institute; J.F. Havlice, Stanford Microwave Laboratory; B.P. Hildebrand, Battelle Northwest; D.R. Holbrooke, Children's Hospital of San Francisco; P.N. Keating, Bendix Research Laboratories; A. Korpel, Zenith Radio Corporation; B.J. McKinley, Lawrence Livermore Laboratory; A.F. Metherell, University of Miami; J. Powers, Naval Postgraduate School; and F.L. Thurstone, Duke University.

Book Description
The latest progress in acoustical holography and related research areas, generally involving imaging by means of acoustic waves, was discussed and treated in depth at the Fourth International Symposium on Acoustical Holography, held in Santa Barbara, California on April 10-12, 1972. This volume contains the proceedings of that symposium. As the papers presented here indicate, a num ber of startling advances have been realized in the state-of-the-art since publication of Volume 3 of Acoustical Holography. Progress has been partic ularly impressive in the field of acoustical imag ing. The Fourth International Symposium represents something of alandmark conference in this respect. The scope of this volume is substantially broad er than the term "acoustical holography' usually implies and encompasses the whole area of visualiza tion, detection, and recording of sound fields whether with long wavelengths, microwaves, or with extrememly short sound wavelengths. The 37 sympo sium papers appear here each as aseparate chapter. In general, the work reported deals mainly with ex perimental and theoretical developments in the a bove areas. This work has significant practical potential use in terms of seismic sensing, under water imaging, non-destructive testing, real-time acoustic microscopy, and medical diagnosis.

Book Description
Holographic Nondestructive Testing presents a unified discussion of the principles and methods of holography and its application holographic nondestructive testing. The book discusses in detail the basic theoretical concepts, the experimental methods for recording holograms, and different specialized holographic techniques. Several kinds of holography are discussed in the beginning chapters such as continuous-wave holography, pulsed holography, and interferometric holography. Other topics covered in the book are holographic surface contouring, holographic correlation, and holographic vibration analysis. Microwave and acoustical holography are the major areas of interest in Chapters 9 and 10. The text serves as an important reference to both engineers and optical scientists.
