Based on the mathematical models of the experimentally fitted spectrum of index inhomogeneities, we
analyze the electromagnetic field scattered from biological tissue. The resulting cross-spectral density
matrices are expressed in spherical polar coordinates and the two-dimensional definition of polarization
could be used. The results show that the polarization characteristics of the far scattered field depend closely
on the types of the tissue.
The expression for the spectral degree of coherence of a far field scattered from a collection of
particles, in the polar spherical coordinate system, is derived. Such an expression may be
reduced to the one in the Cartesian coordinate system in the special case when the two points
considered are in the same radial direction.
On the basis of the angular spectrum representation of stochastic, statistically stationary
scalar fields, the Rytov's perturbation technique for propagation in weakly fluctuating
media and the first Born approximation for weak scattering, we develop a technique for
transmission of stochastic fields through turbulence containing randomly distributed
particles. Results for transmission of the deterministic (laser) field may be obtained
from our general results as a limiting case. We show how our technique can be applied
specifically for the atmospheric turbulence, but in general can also be of interest for
propagation in oceanic turbulence and biological tissues.
