• Goodman, Introduction to Fourier Optics, W. H. Freeman ì ì ð. this comprehensive textbook is the standard reference when it comes to Fourier optics. these two papers discuss the relationship between Fourier optics, ray optics and lightfields, and the Fourier analysis is a ubiquitous tool that has found application to diverse areas of physics and engineering. Goodman focuses on applications in optics, and in particular with applications to diffraction, imaging, optical information processing, holography, and optical communications.
