The transformation of generalized radiance by space-invariant linear systems, based on Walther’s second definition is analyzed. The transfer function for a generalized radiance function is introduced. Its form in the case of quasihomogeneous sources is discussed on the basis of two important examples: free space and an isoplanatic optical system.
