Time-resolved Diffusion theory

Examples

The following figures illustrate the time-resolved transport of light from an impulse isotropic point source of energy within a homogeneous unbounded medium with absorption and scattering properties.

The simulation parameters for the medium are µ_a = 1.0 cm^-1, µ_s(1 - g) = 10.0 cm^-1, n_t = 1.33. The total impulse energy is U_o = 1 J

The fluence rate F(r,t) is plotted versus r at three timepoints: t = 5, 100, and 1000 ps.
