Abstract

New generalizations of the basic radiometric concepts of radiance, radiant emittance, and radiant intensity to fields generated by a two-dimensional stationary partially coherent source are made. It is explicitly shown how they are related to the cross-spectral density of the source. Such new definitions are consistent with the postulates of traditional radiometry.
