The spatial coherence between two points, lying on the propagation axis and which are illuminated by a finite extended, quasi-monochromatic, spatially incoherent light source, is studied. We show a Fourier transform relation between the complex degree of coherence and the quadratic radial distribution of the source, and propose two interferometric systems to measure the degree of coherence.
