Wigner distribution moments measured as fractional Fourier transform intensity moments

Martin J. Bastiaans and Tatiana Alieva

It is shown how all global Wigner distribution moments of arbitrary order can be measured as intensity moments in the output plane of an appropriate number of fractional Fourier transform systems (generally anamorphic ones). The minimum number of (anamorphic) fractional power spectra that are needed for the determination of these moments is derived.
