1. Resource Description

   This software is used for the analysis of one dimensional light transport in skin. It accounts for superficial melanin and otherwise average, homogeneous skin tissue underneath. The software can be used to determine the amount of melanin, water, bilirubin, and beta-carotene in the sample as well as its O2 saturation from scattering data. The method can be applied to other tissues as well as semi-infinite, homogeneous tissue. It is also extendable to multi-path length methods using optical fiber techniques, thus allowing analysis of multi-layer skin.
