Fourier Optics in Examples FOURIER.TEX KB 20020205 KLAUS BETZLER1,FACHBEREICH PHYSIK,UNIVERSITAT¨ OSNABRUCK¨ This short lecture note presents some two-dimensional optical structures and their calculated Fourier transforms. These can be regarded as the respective far-field diffraction patterns. As an addition to textbooks, it may present some visual help
Figure 1: Fourier Transform by a lens. L1 is the collimating lens, L2 is the Fourier transform lens, u and v are normalized coordinates in the transform plane.

A good example is what the human ear makes as it receives an audio waveform and transforms it, breaking it down into different frequencies (which is what
A signal can be decomposed into a sum of sinusoids: 1D (a), 2D (b), 3D (c). Page 7. Prof. Propagation in a lens-like, absorptive medium. 7.8. Fourier optics.
