Meeting the needs of experienced professionals and newcomers to the field, this volume presents major optical measurement procedures-including new work from the authors' laboratory-and offers critical background on optical components and systems, giving access to essential information on modern optics gathered from a range of literature sources. This resource fully describes the capabilities and applications of semiconductor laser diodes used in fiber optics communications and sensors ... refracting, diffracting, reflecting, thin-film, and polarization elements . . . optical metrology . . . Fourier transform processing, image subtraction, and other operations ... coherent and incoher­ent fiber optic sensors . . . and more. This self-study aid also supplies explanatory illustrations, display equations, simplified discussions, and briefly reviews optical surface sensing, surface evaluation, ellipsometry, and laser anemometry. This guide works as a vital reference for optical, laser, photo-optical, electrical, mechani­cal, and industrial engineers; optical physicists; photonic scientists; metrologists; and holographers; and serves as a useful text for graduate students in applied optics training programs or courses.
