Paper Abstract

In this work a method for retrieving the magnitude and phase of the complex degree of spatial coherence is shown. To apply it only the recording of the spot intensity is required. Afterwards, centered reduced moments of the spot are calculated, in order to use them as coefficients of a series to expand the complex degree of spatial coherence. Experimental results for Schell-model spots are shown. The Fourier spectra corresponding to the experimentally recorded sots, are calculated in order to show the equivalency between the proposed method and the Fourier one.
