I was reading about this Fourier transforming property of lens,when I came by the experimental setup for Fourier optics(with laser and a 4f correlator system).Part of the setup was that of Fraunhofer diffraction and we get the Fourier transform of the aperture at the focal point of first lens.
But then a simple setup for Fraunhofer diffraction,which need not consist of a lens, could do the Fourier transform,why is said that the lens has the transforming property?
