Light transport in laser irradiated turbid media, application in medicine and image processing

Much effort is being made in the study of light propagation in human tissue due to the development and wide use of lasers for surgical and therapeutic applications. When a picosecond light pulse is incident on biological tissue, part of the light is reflected back owing to specular surface reflection and the rest of the light penetrates the tissue and encounters multiple scattering and absorption processes. An analysis has been presented for modeling of light distribution in human tissue. The influence of the refractive index, scattering phase function and scattering albedo on light distribution in laser irradiated tissue has been demonstrated.
