Paper Abstract

We consider photon migration in biological tissue and other highly scattering inhomogeneous turbid media. The weight Monte Carlo algorithm imitates the transport of photons between shortly separate source and detector areas of the fiber optic probe by letting the photons carry out a random walk. Considering spatial photon weight distribution on the surface of the simulated semi-infinite medium we show the influence of refractive index mismatching, absorption and anisotropy of the medium on the spatial photon weight distribution on the detector. The understanding of the role of photon portions in the detected signal is important for identification of dominating parts of the reflected light on the detector and as a corollary spatial detector depth sensitivity of back-scattered light, that is important for quantitation of many measurements of the light transport into complex turbid highly scattering media.
