Figure 3.

Plots showing the effect on the SOI when various optical properties are changed. The SOI is most sensitive to changes in the fraction f of light scattering structures which are anisotropic. Changing the values of μ_a and μ_s has almost no effect on the SOI. Likewise, when the anisotropy factors g₀ and g_⊥ are both varied in the same manner, there is little effect on the SOI. However, when the ratio between g₀ and g_⊥changes, the relative amounts of isotropic and anisotropic scattering changes, leading to a change in the SOI. In the graph above, increasing g₀ while g_⊥is fixed leads to an increase in the SOI due to the decrease in isotropic scattering.
