Abstract

The development of experimental methods that distinguish between light from objects with a similar color temperature and polarization presents a significant practical problem. In this paper, we demonstrate that the two-point correlation function (and its resultant correlation length) of a black body with an extended angular spectrum significantly differs from that of a black body with a narrow angular one. Using these results, we discuss an interferometric method as a possible experimental tool for discriminating between objects with the same color temperature but having different angular spectra.
