Abstract
It was recently shown that there is a formal similarity between 1- and 2-D canonical operators.1 This immediately generalizes all previous results in 2-D Fourier optics to nonorthogonal systems. In particular, the analysis of Nazarathy and Goodman2 goes through as before with no change in the logic. The spatial dispersion relation now expresses pz as a function of px and py, where pi is the optical direction cosine in the ith direction. This leads to the linear scalar transfer function for Fourier optics in three dimensions. Similar results can be derived in related fields, such as for anisotropic Gaussian-Schell model sources.
