Quasi-geometrical Paraxial Approach to Fraunhofer Diffraction by Thick Planar Objects Using Phase-space Signal Representations

Abstract

Quasi-geometrical techniques for calculating the Fraunhofer diffraction produced by some thick objects are related to phase-space signal representations, such as the Wigner distribution function. In this way, the properties derived from these functions can be applied directly to obtain an adequate display of the corresponding diffraction patterns.
