✦ Synopsis

An expression is derived for the cross-spectral density matrix, valid in the paraxial region of the far field, generated by a planar blackbody source. With the help of it we determine the spectral degrees of polarization and of cross-polarization of the far field.

It has been shown in a recent publication that in order to calculate the changes which the degree of polarization, the degree of coherence and the spectrum of a random electromagnetic beam undergo as the beam propagates, it is necessary to know the 2 Γ‚ 2 cross-spectral density matrix of the fluctuat
