Consequences of sampling an image and Fourier planes in a numerical light propagation model based on the Helmholtz-Kirchhoff approximation

Abstract

The numerical model of the light propagation phenomenon based on the Helmholtz-Kirchhoff approximation has been analyzed. The model is based on the fast Fourier transform algorithm. It is proved that the fast Fourier transform algorithm limits the class of describing phenomena to the Talbot effects.
