| RTE numerical solution methods: Monte Carlo | Prev topic | Next topic |
The Monte Carlo (MC) method of solving the radiative transfer equation (RTE) reproduces numerically the stochastic process of scattering and absorption of single photons by a light scattering-absorbing medium (for example, Mobley CD 1994, Ch. 6, see also radiative transfer equation, solution methods). This method is based on following the photon histories in a medium (tracing photon paths, for example, Attenuation of light: Contributing processes) and does not restrict the geometry of radiative transfer. Hence, inhomogeneous media and media with odd shapes (for example, broken cloud fields: Zuev VE and Titov 1995) can be investigated using the MC method. The vector nature of a polarized light field can be taken into account (for example, Bartel S and Hielscher 2000, Hansen and Travis 1974). [AAK]
The MC method requires processing of a very large number of photon histories in order to produce reasonably smooth results. Hence various approaches have been used to process the photon histories more efficiently, for example, the backward propagation (backtracking) - photons are emitted from a detector instead from a light source (for example, Lu X and Hsu 2004).
