Fundamentals of Diffraction and Image Formation


One of the most remarkable and most useful properties of a converging lens is its natural and extremely simple ability to perform a two-dimensional Fourier transform. This convenient property of the optical domain has no equivalence in the electronics domain, where an analogue Fourier transform operation requires cumbersome and expensive frequency analyzers.
