For example, if we use k = 2 π ν as the frequency variable, then Eqs. and become For example, Fourier Optics is NOT an extension of the Huygens-Fresnel (or, more corrrectly, the Stratton-Chu) Green's function formulation. In fact, the two have NOTHING to do with one another!!! The Stratton-Chu formulation assumes a source distribution, in which each point source gives rise to a Green's fucntion field.

I am in high-school and planning on basing a research essay on the topic of Fourier Optics. 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.

For more advanced study, the latter chapters and appendices provide methods and examples for modeling beams and pupil functions with more complicated structure, aberrations, and partial coherence. For a student in a course on Fourier optics, this book is a concise, accessible, and practical companion to any of several excellent textbooks on Fourier optical theory.
