Abstract:
Sprays, aerosols as well as other industrially relevant turbid media can be
characterized by light scattering techniques. However these techniques often
fall into the intermediate scattering regime where the average number of times a
photon is scattered is too great for single scattering to be assumed, but too
few for the diffusion approximation to be applied. We present the results of
theoretical study provided details of scattering of laser radiation in the
intermediate single-tomultiple scattering regime. Crossed fiber optic source-
detector geometry is considered to separate the intensity of single scattering
from higher scattering orders. A quantitative analysis of scattering orders in
the intermediate single-tomultiple scattering regime is presented. Agreement
between the analytical and Monte Carlo techniques both used for the calculation
of double light scattering intensity is demonstrated. Influence of detector
numerical aperture on the scattering orders is shown for the intermediate
single-to-multiple scattering regime. The method used can be applied to verify
analytical results indirectly against experiment via Monte Carlo calculations
that include the imperfections of the experiment.
