This is a comprehensive, applications-oriented introduction to geometrical optics, wave optics, and modern optics. Contains new chapters on laser beam characteristics and nonlinear optics, expanded coverage of fiber optics, new sections on ray tracing, thick lens, the Doppler effect, and evanescent waves, and valuable coverage of matrix treatment of polarization, Fraunhofer diffraction, Fourier optics, and more. An ideal introductory guide for the physics instructor, specifically those concentrating on optics.
