The von Neumann entropy of N interacting pencils of radiation is analyzed by using their spectral density matrix. When the cross-spectral density is the same for all pairs of pencils, the entropy is evaluated in closed form as a function of Barakat's N-fold polarization measures. Some technical and historical remarks are made concerning the Planck-von Laue entropy of such pencils. 16 refs., 3 figs.
