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.

  10. Equivalent but formally different generalizations of Walther’s definition, valid at points throughout the half-space z > 0, are considered in Refs. 11 and 12. The function Bν(r, s) defined by Eq. (8) may be regarded as an analog of the Wigner distribution function well known in quantum mechanics.13
