JOURNAL OF QUANTITATIVE SPECTROSCOPY & RADIATIVE TRANSFER
This work continues developing the analytical theory of polarized light tra
nsfer through scattering media and simplification of the Green's matrix of
the problem with splitting the equations for Green's matrix elements starte
d in our previous paper (Zege EP, Chaikovskaya LI. JQSRT 1996;55:19-31). Th
e specific problem is the propagation of linearly polarized light, which is
governed by the central block of the Green's matrix with elements (2,2), (
2,3), (3,2), (3,3). The small parameter of the propagation problem is a val
ue, which characterizes the rotation of the polarization plane in a near-fo
rward scattering event. For a macroscopically isotropic medium with large s
cattering particles this value is always small. A new set of transfer equat
ions for linearly polarized light propogation and scattering is given, spli
tting of this equation having been achieved. The more forward elongated the
medium phase function is the more accurate the solution to the problem. An
effective iteration procedure to solve the original set of equations is su
ggested. It is shown that the linearly polarized light transfer problem red
uces to a scalar problem and can be solved analytically for small-angle for
ward propagation and near-backward scattering. (C) 2000 Elsevier Science Lt
