Abstract

The angular and temporal distributions of light scattered around the backward direction from biological tissues are measured. An enhancement of scattered light intensity around the backward direction, which is associated with the weak photon localization, is observed. The transport mean free path lt and the absorption length la of the light in biological tissue can be obtained from the angular line shape of the coherent peak. The values lt and la can also be obtained from the temporal profile of the scattered pulse.
