Time-resolved optical backscattering from highly scattering media

Abstract

A time-resolved backscattering model, which combines a single large-angle scattering with multiple small-angle scattering‘ is used to produce scattered light profile about the medium. While a multiple small-angle scattering leads to light at near-forward direction, a single large- angle scattering transfers the direction of light to the backward hemisphere. This model can be served as a forward model for image reconstruction of highly scattering media, since inhomogeneity of the medium is included in the model. Some multidimensional integrals can be evaluated analytically, which greatly saves computational time.
