: One of the most critical insights is that a thin lens naturally performs a 2D Fourier transform of the light field at its front focal plane, projecting it onto the back focal plane. Scalar Diffraction Theory

Measures how well the system transfers contrast from the object to the image. : One of the most critical insights is
A modern "Goodman solution" for a pupil mask (say, a hexagonal telescope aperture) is not a closed-form sinc function. It looks like this (pseudocode): It looks like this (pseudocode): In the study
In the study of modern optics, few texts have maintained the relevance and authority of Joseph W. Goodman’s Introduction to Fourier Optics . First published in 1968 and subsequently revised, the text treats optical phenomena—such as diffraction and imaging—as linear filtering operations. However, the transition from the abstract concepts of linear algebra to the physical reality of wave propagation is often a stumbling block for students.
This is the only numerically stable way to propagate light in software. It works because it is linear and preserves evanescent waves (if coded correctly).
