This book was released on 1974 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: When a hologram storing more than one wave is illuminated with coherent light, the reconstructed wave fronts interfere with each other or with any other phase-related wave front derived from the illuminating source. This multiple wave front comparison is called holographic interferometry, and its application is called holographic nondestructive testing (HNDT). The theoretical aspects of HNDT techniques and the sensitivity of the holographic system to the geometrical placement of the optical components are briefly discussed. A unique HNDT system which is mobile and possesses variable sensitivity to stress amplitude is described, and experimental evidence of the application of this system to the testing of the hidden debonds in a ceramic-epoxy-fiberglass structure used for sample testing of the radome of the Pershing missile system is presented.

Available in PDF, EPUB and Kindle. Book excerpt: This book covers a wide range of measurement techniques broadly referred to as Optical Metrology, with emphasis on their applications to nondestructive testing. If we look separately at each of the two terms making the generic name Optical Metrology, we find a link to two of the most distinctive aspects of humans: a particularly well developed sense of vision and a desire to classify things using numbers and rules. Of all our five senses, vision is certainly the most developed and the closest to the rational part of our brain. It can be argued that our memory is strongly dependent on images and the brain is particularly good at processing the stimuli received from these images to extract information. Measuring, sizing and counting are, on the other hand, among the fundamental building blocks of modern society. The use of abstract quantities like size, value or intensity has simplified the description of complex enquiry and is the basis of modern science and economy. Hence, it would seem natural that the combination of two such basic aspects should result in the birth of a new field of science. However, it is known that his has not been the case. Optical Metrology remains classified as a group of special techniques used mainly in niche applications. Optical Metrology may be rightly described as an ensemble of techniques in which fields such as physics, electrical and mechanical engineering, and computer science merge and blend in new ways. This book is intended as a tribute to the career of Professor Léopold Pflug. By looking back at his lifelong commitment to the application of optical metrology to the service of engineering sciences, more particularly devoted to the observation of the real behavior of structural components, one can retrace the major revolutions that have taken place in this domain. Starting his activity in 1971 as the head of the Laboratory for Stress Analysis at the EPFL in Switzerland, he first employed photoelasticity as a tool to improve the understanding of the real behavior of complex structures. However he soon recognized the necessity of working with the real materials used to build these structures instead of on replicas made of optically birefringent materials. He then focussed on the use of moiré techniques which sparked his fascination with laser-based holography and speckle-based methods. The advent of information technology led him to open up to the use of ESPI and digital image processing techniques. Finally, in the mid 1990s he became interested in the use of optical fibers as a tool for sensing deformations inside structures, not only on their surfaces as in the case of whole-field methods. It is interesting to note the parallel in the evolution of optical metrology vis à vis developments in other fields: the development of lasers led to holographic interferometry, the availability of frame-grabbers led to ESPI and the emergence of fiber optic communications opened the way to the development of fiber optic sensors. This puts in sharp perspective the strong dependence of optical metrology on the latest technology for its development. Also interesting to note is that all fields in optical metrology touched upon by Professor Pflug are still of great relevance, as shown by the contributions in this volume. This book is, however, not intended as a commemoration, rather as an occasion to review the trends and undercurrents that are driving the field of optical metrology, with emphasis on nondestructive testing. All the authors were asked to summarize the recent achievements in their respective fields and to speculate about the future. As a result it has become apparent that it is difficult although not impossible to spot general trends in these disparate fields. Optical metrology has considerably benefited from some of the most important innovations of the recent past: lasers, computers and fiber optics communication, all of which found their direct inspiration from the developments in the world of electronics. In recent years we have also witnessed a shift of power from states to corporations. This has created the need to produce quick results useful to industry. Optical nondestructive testing has certainly adapted to this evolution, and several contributions in this book show that the researchers in this field understand the importance of developing technology that can be used by the industry to solve specific problems. We should also not forget that optical nondestructive testing is essentially a "service technology" and should as such not only focus on serving its clients in the best possible way, but also should continually emphasize, extend and enhance its services to new users still unaware of its potential. Hopefully this book will help in spreading awareness of the potentials of optical metrology and in focusing on the challenges of the future.

Available in PDF, EPUB and Kindle. Book excerpt: Holographic Interferometry provides a valuable and up-to-date source of information in the rapidly expanding field. The eight specialists` contributions cover the principles and methods currently in use. The scope of the book has been limited to the study of opaque object and ample space has been devoted to a comprehensive treatment of the phenomena of fringe formation, with a particular emphasis on the quantitative evaluation of the holographic interference fringe patterns. The emergence of computer-aided fringe analysis and phase-shifting techniques have simplified considerably the quantative real-time measurements of object shapes and deformations. The last two chapters provide a reasonably detailedoverview of full-field holographic methods for the measurement of shapes, displacements, dervatives, difference displacements and vibrations.
Download or read book Holographic and Speckle Interferometry written by Robert Jones and published by Cambridge University Press. This book was released on 1989-01-26 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Holographic and speckle interferometry are optical techniques which use lasers to make non-contracting field view measurements at a sensitivity of the wavelength of light on optically rough (i.e. non-mirrored) surfaces. They may be used to measure static or dynamic displacements, the shape of objects, and refractive index variations of transparent media. As such, these techniques have been applied to the solution of a wide range of problems in strain and vibrational analysis, non-destructive testing (NDT), component inspection and design analysis and fluid flow visualisation. This book provides a self-contained, unified, theoretical analysis of the basic principles and associated opto-electronic techniques (for example Electronic Speckle Pattern Interferometry). In addition, a detailed discussion of experimental design and practical application to the solution of physical problems is presented. In this new edition, the authors have taken the opportunity to include a much more coherent description of more than twenty individual case studies that are representative of the main uses to which the techniques are put. The Bibliography has also been brought up to date.
