An account is given of two methods of obtaining information on the complex-valued spatial coherence function, allowing the derivation of the intensity distribution of a noncoherent planar object. In the first of the methods, the cosine and sine of the phase argument are determined by means of triple- and quadruple-intensity correlations; in the second method, the hologram of a noncoherent object is formed by encoding the complex-valued spatial coherence function on a photographic film, by means of a self-referencing interferometer. This latter record allows the reconstruction of the noncoherent source object by recourse to the same interferometric arrangement.
