Abstract
Phase-space tomography is experimentally demonstrated for the determin ation of the spatially varying amplitude and phase of a quasi-monochro matic optical field by measurements of intensity only. Both fully and partially coherent sources are characterized. The method, which makes use of the fractional-order Fourier transform, also yields the Wigner distribution of the field and works in one or two dimensions.
