摘要

This study utilizes experimentally validated Monte Carlo simulations to identify a mathematical formulation of the reflectance intensity collected by a single fiber probe expressed in terms of the reduced scattering coefficient ((mu)_(s)~(')), fiber diameter d_(fiber), and a property of the first two moments of the scattering phase function (gamma). This model is then utilized to accurately obtain wavelength-dependent estimates of (mu)_(s)~(')(lambda) and gamma(lambda) from multiple single fiber spectral measurements of a turbid medium obtained with different diameters. This method returns accurate descriptions (mean residual <3percent) of both (mu)_(s)~(') and gamma across the biologically relevant range.
