Diffraction, Fourier Optics and Imaging: 30: Ersoy, Okan K.: Amazon.se: Books. Learn Fourier and diffractive optics through examples and computer simulation.

This kind of transformation, where a plot of light distribution is transformed into plot of spatial frequency is an example of a Fourier transformation and is a conceptual starting point for Fourier optics.

Here S is the object distance, f is the focal length of the lens, r2 f = x 2 f + y 2 f are coordinates in the focal plane, F(u;v) is the Fourier transform of the object function, u = ¡xf=‚f, and v = ¡yf=‚f. Fourier optics is the study of classical optics using Fourier transforms, in which the waveform being considered is regarded as made up of a combination, or superposition, of plane waves. It has some parallels to the Huygens–Fresnel principle, in which the wavefront is regarded as being made up of a combination of spherical wavefronts whose sum is the wavefront being studied. A key difference is that Fourier optics considers the plane waves to be natural modes of the propagation Example: the Fourier Transform of a Gaussian is a Gaussian! 22 2 exp exp( )exp( ) exp( /4 ) Fat at jtdt a 0 t exp( ) at2 0 exp( /4 ) 2 a There are other examples of functions who are their own Fourier transform.

L1 is the collimating lens, L2 is the Fourier transform lens, u and v are normalized coordinates in the transform plane.

Many of the ordinary properties of the Fourier transform are valid unchanged even for the discrete Fourier transform. This means for example that the DFT is linear, scaling affects both the frequency and the amplitude, and a spatial displacement only affects the phase of the transform and so on.
