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.

Ultrasonic methods have been very popular in nondestructive testing and characterization of materials. This book deals with both industrial ultrasound and medical ultrasound. The advantages of ultrasound include flexibility, low cost, in-line operation, and providing data in both signal and image formats for further analysis. The book devotes 11 chapters to ultrasonic methods. However, ultrasonic methods can be much less effective with some applications. So the book also has 14 chapters catering to other or advanced methods for nondestructive testing or material characterization. Topics like structural health monitoring, Terahertz methods, X-ray and thermography methods are presented. Besides different sensors for nondestructive testing, the book places much emphasis on signal/image processing and pattern recognition of the signals acquired.

Maximizing reader insights into the use of thermography, specifically pulsed and pulse phase thermography (PT and PPT), for the identification of kissing defects in adhesive bonds, this thesis focuses on the application of PT and PPT for the identification of a range of defect types in a variety of materials to establish the effect of material properties on identification of defects. Featuring analysis of a numerical model developed to simulate the thermal evolution created during a PT or PPT experiment, after validation through a series of case studies, this model is then used as a predictive tool to relate defect detectability to the thermal property contrast between defect and bulk materials. Demonstrating a means of producing realistic kissing defects in bonded joints where insufficient thermal property contrast exists defects have a limited effect on heat propagation through a component and therefore are not detected using PT or PPT, this thesis discusses the addition of a small load to bonds containing kissing defects which was found to open the defects sufficiently to enable their detection. A low cost infrared detector, Flir Tau320, is compared to the research based photon detector, Flir SC5000, and is shown to be suitable for application in PT, thus enabling a significantly lower cost tool to be developed.

This book presents a detailed description of the most common nondestructive testing(NDT) techniques used for the testing and evaluation fiber-reinforced composite structures, during manufacturing and/or in service stages. In order to facilitate the understanding and the utility of the different NDT techniques presented, the book first provides some information regarding the defects and material degradation mechanisms observed in fiber-reinforced composite structures as well as their general description and most probable causes. It is written based on the extensive scientific research and engineering backgrounds of the authors in the NDT and structural health monitoring (SHM) of structural systems from various areas including electrical, mechanical, materials, civil and biomedical engineering. Pursuing a rigorous approach, the book establishes a fundamental framework for the NDT of fiber-reinforced composite structures, while emphasizing on the importance of technique’s spatial resolution, integrated systems analysis and the significance of the influence stemming from the applicability of the NDT and the physical parameters of the test structures in the selection and utilization of adequate NDT techniques. The book is intended for students who are interested in the NDT of fiber-reinforced composite structures, researchers investigating the applicability of different NDT techniques to the inspections of structural systems, and NDT researchers and engineers working on the optimization of NDT systems for specific applications involving the use of fiber-reinforced composite structures.

This book was proposed and organized as a means to present recent developments in the field of nondestructive testing of materials in civil engineering. For this reason, the articles highlighted in this editorial relate to different aspects of nondestructive testing of different materials in civil engineering—from building materials to building structures. The current trend in the development of nondestructive testing of materials in civil engineering is mainly concerned with the detection of flaws and defects in concrete elements and structures, and acoustic methods predominate in this field. As in medicine, the trend is towards designing test equipment that allows one to obtain a picture of the inside of the tested element and materials. From this point of view, interesting results with significance for building practices have been obtained
