Abstract
Generalized moments for beams with or without diffraction influence are introduced. Their ABCD-transformation laws are shown theoretically as well as experimentally. The generalized moments are defined from the Wigner function with a window function which improves convergence of the moments integrals. The window function is applied in a covariant way so that the ABCD-transformation properties of the moments become evident. The determination of the generalized moments from beam intensity measurements and their behavior in optical systems is shown from numerically simulated data.
