I was looking at the derivations behind the Fourier transform and the fact that the Fourier transform of the aperture function is the diffraction pattern in Fraunhofer diffraction. • Goodman, “Introduction to Fourier Optics,” W.

The corresponding calculations, which often involve one-dimensional or two-dimensional integrals, can sometimes be done with purely analytical means.
