Rajpal S. Sirohi Introduction to Optical Metrology

Annotation

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, moir phenomenon, photoelasticity, and microscopyDescribes the different principles used to measure the refractive indices of solids, liquids, and gasesPresents methods for measuring curvature, focal length, angle, thickness, velocity, pressure, and lengthDetails techniques for optical testing as well as for making fiber optic- and MEMS-based measurementsDepicts a wave propagating in the positive z-direction by ei(I t - kz), as opposed to ei(kz - I 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.
