The accurate measurements of surface topography are becoming important to many applications in both engineering and science. Optical interferometry is considered a preferable technique for featuring accurate 3D surface profiling since it is non-contacting, non-destructive and highly accurate. In combination with computers and other electronic devices, optical interferometry has become faster, more reliable, more convenient and more robust. There is now a wealth of new optical interferometry techniques on the market, or being developed in academia, that can measure surface topography with high precision. Each method has both its strong points and its limitations. This book explains in detail the basics of optical interferometry, their common language, generic features and limitations, and their simulation and uncertainties. Moreover, it provides an introduction to new frontiers in optical interferometry, including terahertz technology and optical frequency combs.

Introduction to Optical Metrology examines the theory and practice of various measurement methodologies utilizing the wave nature of light. The book begins by introducing the subject of optics, and then addresses the propagation of laser beams through free space and optical systems. After explaining how a Gaussian beam propagates, how to set up a collimator to get a collimated beam for experimentation, and how to detect and record optical signals, the text: Discusses interferometry, speckle metrology, moiré phenomenon, photoelasticity, and microscopy Describes the different principles used to measure the refractive indices of solids, liquids, and gases Presents methods for measuring curvature, focal length, angle, thickness, velocity, pressure, and length Details techniques for optical testing as well as for making fiber optic- and MEMS-based measurements Depicts a wave propagating in the positive z-direction by ei(ωt – kz), as opposed to ei(kz – ωt) Featuring exercise problems at the end of each chapter, Introduction to Optical Metrology provides an applied understanding of essential optical measurement concepts, techniques, and procedures.

Optical Metrology is a rapidly expanding field i'n both its scientific foundations and technological developments, being of major concern to measurements, quality control, non-destructive tes ting and in fundamental research. In order to define the state-of-the-art, and to evaluate pre sent accomplishments, whilst giving an appraisal of how each of the particular topics will evolve the Optical Metrology-anAdvancedStudy Institute was organized with a concourse of the world's acknowledged experts. Thus, the Institute provided a forum for tutorial reviews blended with topics of current research in the form of a progressive and comprehensive presentation of recent promising developments, lea ding techniques and instrumentation in incoherent and coherent optics for Metrology, Sensing and Control in Science, Industry and Biomedici ne. Optical Metrology is a very broad field which is highly inter disciplinary in its applications, and in its scientific and technolo gical background. It is related to such diverse disciplines as physi cal and chemical sciences, engineering, electronics, computer scien ces, biological sciences and theoretical sciences, such as statistics. Although there was an emphasis on photomechanics and industri al applications, a marked diversity was reflected in the different background and interests of the participants. The vitality and viabi lity of the discipline was enhanced not only by the encouraging number of young scientists and industrialists participating and authoring, but also by the remarkably promising prospects found in x the practical applications supported by advanced electronic hybridi zation.

The main objective of this book is to present the basic theoretical principles and practical applications for the classical interferometric techniques and the most advanced methods in the field of modern fringe pattern analysis applied to optical metrology. A major novelty of this work is the presentation of a unified theoretical framework based on the Fourier description of phase shifting interferometry using the Frequency Transfer Function (FTF) along with the theory of Stochastic Process for the straightforward analysis and synthesis of phase shifting algorithms with desired properties such as spectral response, detuning and signal-to-noise robustness, harmonic rejection, etc.

The measurement and characterisation of surface topography is crucial to modern manufacturing industry. The control of areal surface structure allows a manufacturer to radically alter the functionality of a part. Examples include structuring to effect fluidics, optics, tribology, aerodynamics and biology. To control such manufacturing methods requires measurement strategies. There is now a large range of new optical techniques on the market, or being developed in academia, that can measure areal surface topography. Each method has its strong points and limitations. The book starts with introductory chapters on optical instruments, their common language, generic features and limitations, and their calibration. Each type of modern optical instrument is described (in a common format) by an expert in the field. The book is intended for both industrial and academic scientists and engineers, and will be useful for undergraduate and postgraduate studies.
