Abstract

A method to retrieve complex coherence of the speckle field from two-point intensity correlation is described and experimentally demonstrated. This is carried out by combining two-point intensity correlation and a holographic principle. Experimental results of the complex coherence function of the speckle fields are presented for two different sources at the scattering plane. For comparison purposes, complex coherence functions of the speckle fields are also analytically evaluated using the van Cittert-Zernike theorem and good agreement between experimental and analytical results confirms the accuracy of our method.
