  As manifested in the similarity relation of diffuse light transport, it is
difficult to assess single scattering characteristics from multiply scattered
light. We take advantage of the limited validity of the diffusion approximation
of light transport and demonstrate, experimentally and numerically, that even
deep into the multiple scattering regime, time-resolved detection of
transmitted light allows simultaneous assessment of both single scattering
anisotropy and scattering mean free path, and therefore also macroscopic
parameters like the diffusion constant and the transport mean free path. This
is achieved via careful assessment of early light and matching against Monte
Carlo simulations of radiative transfer.
