A general connection between interferometry and radiometry is studied on the basis of a new relationship between Walther’s first generalized radiance function and the mutual coherence function for polychromatic fields. New results include a definition of the generalized radiance function that is valid even for nonstationary fields and a principle of novel radiometry that retrieves three-dimensional radiance in the direction-frequency domain from the three-dimensional mutual coherence function. Radiometric interpretations of interferometric multispectral imaging are given as illustrative examples of this new principle.
