Unique within the field for being written in a tutorial style, this textbook adopts a step-by-step approach to the background needed for understanding a wide range of full-field optical measurement techniques in solid mechanics. This method familiarizes readers with the essentials of imaging and full-field optical measurement techniques, helping them to identify the appropriate techniques and in assessing measurement systems. In addition, readers learn the appropriate rules of thumb as a guide to better experimental performance from the applied techniques. Rather than presenting an exhaustive overview on the subject, each chapter provides a concise introduction to the concepts and principles, integrates solved problems within the text, summarizes the essence at the end, and includes unsolved problems. With its coverage of topics also relevant for industry, this text is aimed at graduate students, researchers, and engineers involved in non-destructive testing for acoustics, mechanics, medicine, diagnosis on artwork and construction, and civil engineering.
Pramod Rastogi received his M.Tech. degree from the Indian Institute of Technology Delhi, and his doctorate degree from the University of Franche Comt? in France. He started his research at the EPFL in Switzerland in 1978. He is the author or coauthor of many scientific papers and the author of book chapters and Encyclopedia articles, and has edited several books in the field of optical metrology. Professor Rastogi is a Fellow of the Optical Society of America (1993) and a Fellow of the Society of the Photo-Optical Instrumentation Engineers (1995). He is also a recipient of the "Het?nyi Award" for the most significant research paper published in Experimental Mechanics (1982).
Erwin Hack holds a diploma in theoretical physics and a Ph.D. in physical chemistry, both from the University of Zurich, Switzerland. Since 1998, he is deputy laboratory head at Empa, the Swiss Federal Laboratories for Materials Science and Technology. His research interest is in full-field optical measurement techniques including speckle interferometry and thermography. He coordinated and participated in European research projects on optical techniques. Dr. Hack regularly publishes in peer-reviewed journals and conferences. He lectures at ETH Zurich on optical methods in experimental mechanics. He is a member of VAMAS TWA26 on full field optical stress and strain measurement, vice-president of the Swiss Society for Non-destructive Testing, and a member of EOS and OSA.
