Abstract
A reversed-wavefront Young interferometer has recently been proposed and demonstrated for a direct measurement of optical coherence. It relies on the creation of a reversed-wavefront replica of an electromagnetic beam in such a way that the coherence function of the initial beam can be mapped out by simple translation of a pair of pinholes in a Young's interference experiment. The same interferometer can, in principle, be used for polarization-dependent coherence measurements, but presents significant challenges. In this paper, we will describe the calibration of the interferometer and show measurements of the polarization-dependent coherence function of two optical sources.
