Rodrigo acknowledges the Spanish Ministry of Science and Innovation for the “Juan de la Cierva” grant. We also thank G. Cristóbal for his valuable discussions on the numerical calculation of the WD.We propose a simple approach for the phase space tomography reconstruction of the Wigner distribution of paraxial optical beams separable in Cartesian coordinates. It is based on the measurements of the antisymmetric fractional Fourier transform power spectra, which can be taken using a flexible optical setup consisting of four cylindrical lenses. The numerical simulations and the experimental results clearly demonstrate the feasibility of the proposed scheme.engjournal articlehttp://dx.doi.org/10.1364/JOSAA.26.001301http://www.opticsinfobase.org/open access535Fractional FourierRetrievalTransformImplementationAlgorithmSystemImageÓptica (Física)2209.19 Óptica Física
