A useful relationship between the fractional Fourier transform power spectra of a two-dimensional symmetric optical beam on the one hand and its Wigner distribution on the other is established. This relationship allows a significant simplification of the standard procedure for the reconstruction of the Wigner distribution from the field intensity distributions in the fractional Fourier domains. The Wigner distribution of a symmetric optical beam is analyzed, both in the coherent and in the partially coherent case.
