Abstract

The technologies of high sensitivity optical spectroscopy analysis on turbid media play an important part in scientific research and biomedical applications. The optical path in which photons travel inside the turbid media generally brings information of the components of the media. This paper introduces a novel method to study some of the properties of turbid media by measuring and analyzing the differences of optic paths of wavelength modulated laser beams experienced in the media. The operating principle to accomplish detecting media information in specified optical length is theoretical analyzed. The Experiments and measurements on the multiple scattering properties in transparent media (water, and air) and turbid media (simulation tissue fluid) are reported in the paper as well.
