An Introduction to Acoustical Holography


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 SOO 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. Tbree symposia whoUy devoted to acoustical holography have been held and tbe papers published in book form. The purpose of this book is to bring together the results of research in acoustical holography, some of it as yet unpublished, under one cover so that workers in holography, nondestructive testing, medical imaging, underwater imaging, and seismic exploration can decide whether this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.




An Introduction to Acoustical Holography


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 The purposeof this book is to bring together the results of research in acoustical holography, some of it as yet unpublished, under one cover so that workers in holography, nondestructive testing, medical imaging, underwater imaging, and seismic exploration can decide whether this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.




Fourier Acoustics


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.




Acoustical Holography


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.




Holographic Nondestructive Testing


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.




Acoustical Holography


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.

Acoustical Holography


Book Description

This volume contains the papers presented at the Seventh International Symposium on Acoustical Imaging and Holography. The meeting was held in Chicago, Illinois U.S.A. on August 30 - September 1, 1976. Since 1967 this series of conferences has served as an international forum for bringing together the many different facets of the ultrasonic visualization field. Medical diagnosis, nondestructive testing, underwater viewing, seismic the mapping, and acoustic analytical microscopy are examples of broad range applications of this technology. Throughly broad in scope, the common denominator that binds this volume together is the application of engineering and physics disciplines to the creation of images by means of ultrasonic waves.

Acoustics, the science of sound, has developed into a broad interdisciplinary field encompassing the academic disciplines of physics, engineering, psychology, speech, audiology, music, architecture, physiology, neuroscience and others. Here is an unparalleled modern handbook reflecting this richly interdisciplinary nature edited by one of the acknowledged masters in the field, Thomas Rossing. Researchers and students benefit from the comprehensive contents spanning: animal acoustics including infrasound and ultrasound, environmental noise control, music and human speech and singing, physiological and psychological acoustics, architectural acoustics, physical and engineering acoustics, medical acoustics and ocean acoustics. The Springer Handbook of Acoustics reviews the most important areas of acoustics, with emphasis on current research. The authors of the various chapters are all experts in their fields. Each chapter is richly illustrated with figures and tables. The latest research and applications are incorporated throughout, e.g. computer recognition and synthesis of speech, physiological acoustics, psychological acoustics, thermoacoustics, diagnostic imaging and therapeutic applications and acoustical oceanography. This new edition of the Handbook features over 11 revised and expanded chapters, new illustrations and two new chapters covering microphone arrays, acoustic metamaterials and acoustic emission. These improvements will make the handbook even more useful as a reference and a guide for researchers and students in every branch of acoustics. Praise for the first edition: "This treatise is a successful attempt to cover in one book the diverse field of acoustics, which ranges from physics to music and from formal mathematics to technological applications. ... It is this reviewer's opinion that a handbook like Rossing's, which covers the whole field of acoustics, serves a real purpose because it not only gives one a chance to see how one's specialty is covered but it also permits one to make a quick survey of other acoustical areas." (Leo Beranek, American Journal of Physics, Vol. 77 (12), December, 2009) "The Springer Handbook of Acoustics falls into that exceptional list. ...every physics department should have a copy available." (John L. Hubisz, The Physics Teacher, Vol. 48, March, 2010) "This handbook is an excellent addition to the acoustics literature. ... The handbook nicely covers both basics and advances in several areas of acoustics. Several chapters provide good mathematical depth, making the handbook useful as a research and technical resource. ...Overall, a very useful educational and research resource. Summing Up: Recommended. Upper-division undergraduates through professionals." (M. G. Prasad, CHOICE, Vol. 45 (5), January, 2008) "This book covers a wide range of topics and the inclusion of musical acoustics, computer and electronic music appeal to me (singer, song-writer, performer and recording studio co-owner). This handbook is probably well suited for an undergraduate-level introduction to an acoustics course. ... The wide range of topics, inclusion of music-related chapters, eye-pleasing presentations and other useful features make this a very good book to have on your shelf." (Tim Casey, International Journal of Acoustics and Vibration, Vol. 13 (1), 2008) "The Springer Handbook of Acoustics comprises 28 chapters written by 33 authors. The Handbook of Acoustics is useful as a source book for anyone who needs or wants to become familiar with the jargon and issues related to a specific subfield of acoustics ... ." (Robert I. Odom, Siam Review, Vol. 50 (3), 2008) The Springer Handbook of Acoustics reviews the most important areas of acoustics, with emphasis on current research. The authors of the various chapters are all experts in their fields. Each chapter is richly illustrated with figures and tables. The latest research and applications are incorporated throughout, e.g. computer recognition and synthesis of speech, physiological acoustics, psychological acoustics, thermoacoustics, diagnostic imaging and therapeutic applications and acoustical oceanography.
