Introduction to Fourier Optics is the standard teaching and reference text for Fourier Optics and optical Information processing. Over the years, applications of these principles have been important in diverse fields such as pattern recognition, image processing, displays, sensors, communications, data storage and imaging systems. Previous editions have included updated material on holography and wavefront modulation. In this most recent edition, a new chapter describes devices and techniques important for optical communications, emphasizing the interplay between time, temporal frequency, space and spatial frequency. Topics such as fiber Bragg gratings, ultrashort pulse shaping and spectral holography are presented in the same clear and understandable yet detailed manner as the other topics in the text. Once again, the use of Fourier techniques provides particular insight into the principles and applications of these important new fields. This latest edition is an outstanding enhancement of this classic text.
