Steady-state diffusion Theory:

Examples

The following figures illustrate the transport of light from a steady-state isotropic point source of power within a homogeneous unbounded medium with absorption and scattering properties.

The steady-state fluence rate F(r) is plotted versus r.

medium: µa = 1.0 cm-1, µs(1 - g) = 10.0 cm-1, nt = 1.33
impulse power: Po = 1 W
