A nine-layered skin tissue model is newly developed for the Monte Carlo simulation of spectral reflectance. The derivation of the necessary parameters for each of the nine layers in the simulation is presented, in which the parameters used in the conventional three-layered model are modified on the basis of some histological findings on skin and reported examples. Using appropriate optical and geometrical parameters, simulated spectra can be produced that agree well with measured spectra. This approach provides a flexible means of spectral fitting to measured results and of estimating changes in the parameters of skin tissue.

Key words: skin tissue, spectral reflectance, Monte Carlo simulation, scattering coefficient, absorption coefficient, spectral fitting
