Paper Abstract

Generalized radiance was introduced for analyzing the behavior of radiant surfaces in any state of spatial coherence. Some of its properties make difficult to interpret it physically. In particular, generalized radiance is a Wigner distribution function that can take positive and negative values, so that it does not have the meaning of an energy flux at all. Supported on the concept of radiator pairs we will express the generalized radiance, the generalized radiant emittance and the generalized radiant intensity first proposed by Marchand and Wolf. Then, we will analyze the extreme cases of spatially coherent and incoherent sources and propose a new physical interpretation for the negative values of the generalized radiance.
