On the Existence of a Radiance Function for a Partially Coherent Planar Source

  • Ari T. Friberg
Conference paper


Since the publication of an important paper by A. Walther [1] in 1968, several authors [2] have studied radiometry taking into account the random nature of the optical wave field. The traditional radiometric quantities, commonly believed to apply to incoherent sources, have been generalized to pertain to planar sources of an arbitrary state of coherence [1,3]. The generalized formalism of radiometry is based on the second-order coherence theory and the generalized radiometric quantities are linear in the correlation function of the wave field at two points in the source plane.

    The radiance is also known as the specific intensity or the brightness. For the customary definition of the radiance see, for example, S. Chandrasekhar, Radiative Transfer (Dover, New York, 1960) Section 1.Google Scholar

    Actually the proportionality factor is trivially dependent on s itself, but this dependence is of no consequence here.Google Scholar
