Spatially resolved reflectance close to source has received a great deal of attention recently. This research is considered to develop a new noninvasive technique for measuring the optical properties of biological media. Using Monte Carlo simulations, we investigated the influence of third-order parameter δ on diffuse reflectance and found that the reflectance decreased with an increase of δ at a short source–detector separation of approximately 0.7–2 transport mean free paths. We show that the effects of two parameters, γ and second-order parameter δ, on the reflectance are contrary. As a result the influence of the second-order parameter γ on the reflectance is irregular when the condition Δ δ Δ γ is not satisfied.
