摘要

A simple and quick approach is used to measure the reduced scattering coefficient (mu(s)') of a semi-infinite turbid medium having a much smaller absorption coefficient than mu(s)'. A laser beam with an oblique angle of incidence to the medium causes the center of the diffuse reflectance that is several transport mean-free paths away from the incident point to shift away from the point of incidence by an amount Delta x. This amount is used to compute mu(s)' by mu s' = sin(alpha(i))/(n Delta x), where n is the refractive index of the turbid medium divided by that of the incident medium and ori is the angle of incidence measured from the surface normal. For a turbid medium having an absorption coefficient comparable with mu(s)', a revision to the above formula is made. This method is tested theoretically by Monte Carlo simulations and experimentally by a video reflectometer. [References: 11]
