Reduced scattering coefficient

Definition: The reduced scattering coefficient measures how much light is scattered by tissue assuming equal probability for the scattering angle (isotropic scattering) without absorption. Besides the absorption coefficient, it is one of the two main optical parameters that model light propagation through tissue in the diffusion approximation. Reduced scattering coefficient can be formulated as: ${mu}_s^{prime}={mu}_s(1-g)$ with $mu_s$ as the scattering coefficient, a measure of how much light is scattered per unit distance when considering single scattering; and $g = <cos(theta) >$ as the anisotropy factor, describing the degree of forward versus backward scattering of light.
