Radiometric model for propagation of coherence.
A radiometric model for the propagation of coherence is formulated, which greatly simplifies the determination of the cross-spectral density and of the spectral degree of coherence of the field at an arbitrary distance from any planar, secondary, quasi-homogeneous source. The radiance function, which plays a central role in this model, satisfies all the postulates of traditional radiometry.
