Interferometry in Speckle Light


Book Description

These proceedings reflect the work presented at the conference "Interferometry in Speckle Light: Theory and Applications", held at the Ecole Polytechnique Federale de Lausanne, (EPFL), the Swiss Federal Institute of Technology in Lausanne, Switzerland. The event took place from September 25 to September 28, 2000. Thanks to the diligence of the authors, this book has been published just in time for the conference. Writing this preface in July, in anticipation of the conference, we have tried to envisage how this book will benefit the quality of discourse between authors and attendees. "Interferometry in Speckle Light: Theory and Applications" results from a bottom-up approach and is original in several ways. This conference is not part of a series; on the contrary, it is a single event. The idea of gathering scientists and engineers for a general discussion on the theory and the practice of interferometry, involving rough, non-optically polished objects, was "in the air". An opportunity of this sort was not provided by any of the conferences scheduled when the present one was conceived. For this reason, it was easy to convince a small number of renowned researchers, all of them active in the field of holographic and speckle interferometry, to organize a conference. To be specific, they are the people listed below as members of the scientific and local committees. At the same time, a particular circumstance, namely the retirement of Professor L. Pflug, helped to detennine the location of the meeting.




Holographic and Speckle Interferometry


Book Description

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.

Laser Speckle and Applications in Optics


Book Description

Laser Speckle and Applications in Optics focuses on developments in laser speckle techniques, with emphasis on the experimental aspect of phenomena and on applications in optics. These applications include interference with scattered light, optical processing of images, and studies of surface roughness as well as displacements and deformations of diffuse objects. This book is comprised of 10 chapters and begins by reviewing the elements of diffraction theory and the properties of speckle in the image of a diffuse object. The discussion then turns to speckle in the near field and interferometry with diffuse light, along with experiments in which interference patterns are produced from photographically superimposed laterally shifted speckle patterns. The following chapters consider optical processing of images modulated by speckle; deformations and displacements of diffuse objects; speckle applications in astronomy; and surface roughness measurements. The final chapter looks at the use of laser speckle to study transparent objects; the average shape of diffuse surfaces; the transfer functions and aberrations of optical systems; and the movement of diffuse objects. This monograph will be of value to physicists and researchers as well as those interested in lasers and optics.

Basics of Interferometry


Book Description

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.




Speckle Metrology


Book Description

Speckle Metrology presents a diverse and wide collection of metrological speckle techniques and applications. The book discusses both theoretical concepts and experimental methods in speckle-based measurements. Some chapters introduce speckle terminology and the physical characteristics of speckle. Other aspects also covered in the book include methodology, system geometries, data reduction procedures, and specific applications. These applications are discussed in detail in individual chapters, such as structures inspection. Adaptation of speckle measurement techniques in video recording and processing technology is also given emphasis in one chapter. Finally, one chapter is dedicated to a discussion on the speckle interferometer as one of the most used instrument in metrological speckle application. This text is a valuable reference to students in the fields of engineering and applied science.




Interferometry


Book Description

Enlarged and updated in 1983, this is the second edition of Dr Steel's popular textbook on interferometry. The text has been revised throughout and major additions have been made to reflect the phenomenal growth of laser techniques and applications. The book provides a general treatment that brings together the many different applications of the interference of light waves, light being used in its most general sense to include all electromagnetic radiation. The applications can cover precise measurement of length, the testing of optical components against a computed hologram, measurements of atmospheric pollution by infrared spectroscopy and many of the methods of radio astronomy and the measurement of size of visible stars. These apparently unrelated methods have a common theory, which the book presents and extends to each main field of application. It shows workers in one field how their problems relate to those in other fields, where they may have been solved already. The book will be found useful by anyone whose work involves one of the many applications of interferometric techniques.
