Vg. Kolinko et al., ON REFRACTION IN MONTE-CARLO SIMULATIONS OF LIGHT TRANSPORT THROUGH BIOLOGICAL TISSUES, Medical & biological engineering & computing, 35(3), 1997, pp. 287-288
To obtain reliable results from Monte-Carlo simulations of light scatt
ering experiments, a statistically accurate procedure for positioning
the photons after refraction between two different scattering media is
necessary. Two statistically equivalent algorithms for calculating th
e position of the photons immediately after crossing an interface are
described and justified.
