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.

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.

Speckle metrology includes various optical techniques that are based on the speckle fields generated by reflection from a rough surface or by transmission through a rough diffuser. These techniques have proven to be very useful in testing different materials in a non-destructive way. They have changed dramatically during the last years due to the development of modern optical components, with faster and more powerful digital computers, and novel data processing approaches. This most up-to-date overview of the topic describes new techniques developed in the field of speckle metrology over the last decade, as well as applications to experimental mechanics, material science, optical testing, and fringe analysis.

This new resource explains the principles and applications of today’s digital optical measurement techniques. From start to finish, each chapter provides a concise introduction to the concepts and principles of digital optical metrology, followed by a detailed presentation of their applications. The development of all these topics, including their numerous methods, principles, and applications, has been illustrated using a large number of easy-to-understand figures. This book aims to not only help the reader identify the appropriate techniques in function of the measurement requirements, but also assess modern digital measurement systems.

Handbook of Optical Metrology: Principles and Applications begins by discussing key principles and techniques before exploring practical applications of optical metrology. Designed to provide beginners with an introduction to optical metrology without sacrificing academic rigor, this comprehensive text: Covers fundamentals of light sources, lenses, prisms, and mirrors, as well as optoelectronic sensors, optical devices, and optomechanical elements Addresses interferometry, holography, and speckle methods and applications Explains Moiré metrology and the optical heterodyne measurement method Delves into the specifics of diffraction, scattering, polarization, and near-field optics Considers applications for measuring length and size, displacement, straightness and parallelism, flatness, and three-dimensional shapes This new Second Edition is fully revised to reflect the latest developments. It also includes four new chapters—nearly 100 pages—on optical coherence tomography for industrial applications, interference microscopy for surface structure analysis, noncontact dimensional and profile metrology by video measurement, and optical metrology in manufacturing technology.

Speckle Phenomena in Optics provides a comprehensive discussion of the statistical properties of speckle, as well as detailed coverage of its role in applications. Some of the applications discussed include speckle in astronomy, speckle in the eye, speckle in projection displays, speckle in coherence tomography, speckle in lithography, speckle in waveguides (modal noise), speckle in optical radar detection, and speckle in metrology. This book is aimed at graduate students and professionals working in a wide variety of fields.

Speckle study constitutes a multidisciplinary area with inherent complexities. In order to conquer challenges such as the variability of samples and sensitive measurements, researchers must develop a theoretical and statistical understanding of both biological and non-biological metrology using dynamic speckle laser. Dynamic Laser Speckle and Applications discusses the main methodologies used to analyze biospeckle phenomena with a strong focus on experimentation. After establishing a theoretical background in both speckle and biospeckle, the book presents the main methodologies for statistical and image analysis. It then deals with the concept of frequency decomposition before moving on to a discussion of fuzzy methods to treat dynamic speckle data. The book dedicates two sections to applications, including agricultural approaches. Additional features include photo images of experiments and software to aid in easy start-up of dynamic speckle usage. A systematic approach to new dynamic speckle laser phenomena, this book provides the physical theory and statistical background needed to analyze images formed by laser illumination in biological and non-biological samples.

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.

Laser measurement technology has evolved in the last years in a versatile and reflationary way. Today, its methods are indispensable for research and development activities as well as for production technology. Every physicist and engineer should therefore gain a working knowledge of laser measurement technology. This book closes the gap of existing textbooks.
