Principles and Applications of Fourier Optics

`All of optics is Fourier optics!' While this statement may not be literally true, when there is one basic mathematical tool to explain light propagation and image formation, with both coherent and incoherent light, as well as thousands of practical everyday applications of the fundamentals, Fourier optics is worth studying. This book contains summaries of the principles of Fourier optics that have been developed over the past hundred years and of many applications over the past fifty years, especially since the invention of the laser. This book is intended as a series of guideposts to improve our world through the applications of Fourier optics.
