Fourier transform theory is of central importance in a
vast range of applications in physical science,
engineering and applied mathematics. Providing a
concise introduction to the theory and practice of
Fourier transforms, this book is invaluable to
students of physics, electrical and electronic
engineering, and computer science. After a brief
description of the basic ideas and theorems, the
power of the technique is illustrated through
applications in optics, spectroscopy, electronics and
telecommunications. The rarely discussed but
important field of multi-dimensional Fourier theory is
covered, including a description of Computer Axial
Tomography (CAT scanning). The book concludes by
discussing digital methods, with particular attention
to the Fast Fourier Transform and its
implementation. This new edition has been revised
to include new and interesting material, such as
convolution with a sinusoid, coherence, the
Michelson stellar interferometer and the van Cittert-
Zernike theorem, Babinet`s principle and dipole
arrays.isbn-9781107645509
