Paper Abstract

A semi-empirical model initiated in 2009 has facilitated clinical investigations of steady-state single-fiber reflectance spectroscopy (SfRS). We demonstrate an integration model for steady-state SfRS. Our model treats the single-fiber diffuse reflectance as the integration of a lever-set spatially resolved diffuse reflectance associated with a light incidence at the center of the fiber over the entire fiber facet. The integration over the collection area with a diameter ݀dfib reproduces the steady-state features of SfRS over the dimensionless reduced scattering μsdfib= [10-2, 103], absorption coefficient μa=[0.001, 1.0] mm-1 and an anisotropy factor ݃g= 0.9 for the Henyey-Greenstein scattering phase function.
