Fractal mechanisms of light scattering in biological tissue and cells

Opt Lett. 2005 Nov 15;30(22):3051-3. doi: 10.1364/ol.30.003051.


We use fractal continuous random media to model visible and near-infrared light scattering by biological tissue and cell suspensions. The power law of the reduced scattering coefficient, the anisotropy factor of scattering, and the phase function are derived with good agreement with experimental results. Implications for spectroscopic tissue diagnosis are discussed.
