Abstract

New definitions of radiance, radiant intensity, and radiant emittance are proposed for planar sources of any state of coherence. They can be uniquely determined without arbitrariness from the cross-spectral density function of the source and satisfy the basic postulates of traditional radiometry. A physically meaningful analogy between the series expansion that defines the new radiance and the Mercer expansion of the cross-spectral density is discussed.
