about this item
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(?t – kz), as opposed to ei(kz – ?t)
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.
Designed as a text useful for the classroom and professionals, this book has been carefully organized and updated to present the techniques, theory and measurements of optical metrology with a simplified approach. It provides a background of optics, lasers and incoherent sources as well as detectors and recoding methods. Various scientific and industrial parameters are covered, including fiber optics. To help the reader gain a deeper understanding of the subject, exercise problems are included at the end of each chapter.
