Radiometry with sources of any state of coherence*

A Critical Study of the Radiative Transfer Approach for the Remote Sensing of Layered Random Media

“…On the other hand the RT equation, as we saw earlier, is an equation for the specific intensity which is a 'phase-space' quantity. Wigner transforms serve as a bridge to link these two quantities [43,9,20,30].…”

Radiative Transfer Theory for Layered Random Media

“…Note that (25) equation, as we saw earlier, is an equation for the specific intensity, which is a 'phase-space' quantity. Wigner transforms serve as a bridge to link these two quantities (Yoshimori, 1998;Friberg, 1986;Marchand & Wolf, 1974;Pederson & Stamnes, 2000). We introduce the Wigner transforms of waves and Green's functions as…”

Radiometry of Partially Coherent Fields. I

“…We have reserved the symbols r and F for the mathematics and introduced new symbols M and L for the radiometric quantities . The angle integrals in relations involving M and L, equation (14), will be limited to (2) . But the full range -oo, oo as in equation (8) The mutual spectral density F has the form of a suitable sharply peaked function .…”

“…Subsequently, in 1974, the formalism was extended, and a more detailed study of several special cases was carried out by Marchand and Wolf [2] . The radiometry of Lambertian sources in the framework of their formalism is also discussed by Winthrop [3] and by Carter and Wolf [4] .…”
