Fractal model of light scattering in biological tissue and cells

Opt Lett. 2007 Jan 15;32(2):142-4. doi: 10.1364/ol.32.000142.

Abstract

The K-distribution, widely used for investigation of fractal scattering in the atmosphere and from surfaces, is applied as a model for light propagation in biological tissue and cells. This leads to simple expressions for the scattering function, anisotropy function, phase function, reduced scattering coefficient, and scattering power. Compared with an alternative previously published model [Opt. Lett.30, 3051 (2005)], the range of allowable power laws is extended into the subfractal regime.
