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.

Digital Speckle Interferometry and Related Techniques provides a single source of information in this rapidly progressing field. Containing contributions from leading experts, it provides the key background information, including the fundamental concepts, techniques, and applications, and presents the major technological progress that has contributed to revitalization in the field over the past fifteen years, including digital speckle photography and digital holographic interferometry.

The Proceedings contain state-of-the-art reviews and original materials related to up-to-date developments in a wide range of optical control methods. They are devoted in particular to shape, displacement and deformation measurement, strain analysis, mechanical behavior evaluation, inspection and non-destructive testing. Three principal classes of methods are under consideration: speckle photography, holographic interferometry and speckle interferometry. Both the state-of-the-art practices and the actual leading-edge techniques are discussed within a single volume, with reference to theoretical backgrounds common to all methods. Usually, similar information is distributed over many specialised works. The book presents both conceptual and practical aspects: theoretical considerations are fully analysed and applications illustrate the emphasis on many experimental aspects.

This practical reference offers state-of-the-art coverage of speckle metrology and its value as a measuring technique in industry.;Examing every important aspect of the field, Speckle Metrology: surveys the origin of speckle displacement and decorrelation; presents procedures for deformation analysis and shape measurement of rough objects; explains particle image velocimetry (PIV), the processing of PIV records, and the design requirements of PIV equipment; discusses the applications of white light speckle methods and the production of artificial speckles; describes the measurement of surface roughness with laser speckles and polychromatic speckles; illustrates semiautomatic and automatic methods for the analysis of Young's fringes; calculates the variation of Young's fringes with the change in the microrelief of the rough surface; and explicates hololenses for imaging and provides design details with aberration corrections for hololense systems.;With over 1500 literature citations, tables, figures and display equations, Speckle Metrology is a resource for students and professionals in the fields of optical, mechanical, electrical and electronics engineering; applied physics; and stress analysis.

This book is for those who have some knowledge of optics, but little or no previous experience in interferometry. Accordingly, the carefully designed presentation helps readers easily find and assimilate the interferometric techniques they need for precision measurements. Mathematics is held to a minimum, and the topics covered are also summarized in capsule overviews at the beginning and end of each chapter. Each chapter also contains a set of worked problems that give a feel for numbers.The first five chapters present a clear tutorial review of fundamentals. Chapters six and seven discuss the types of lasers and photodetectors used in interferometry. The next eight chapters describe key applications of interferometry: measurements of length, optical testing, studies of refractive index fields, interference microscopy, holographic and speckle interferometry, interferometric sensors, interference spectroscopy, and Fourier-transform spectroscopy. The final chapter offers suggestions on choosing and setting up an interferometer.
