Publisher's Synopsis
This introductory text aims to provide a guide for understanding the principles of modern Fourier optics and their role in the formation and processing of images. It intends to meet a need for an elementary explanation of the common themes of Fourier optics in a wide variety of imaging applications, both optical and otherwise. This edition has been revised to extend the range of possible applications, and includes problems on the core chapters.;The book also provides a means for understanding delta functions, frequency space, convolution and correlation, as well as Fourier series and transforms. Other additions include appendices giving summary notes on main chapters; a section on incoherent digital computer-based processing, and an appendix on signal processing. The book also studies radioastronomy and modern Fourier transform spectroscopy.
