Abstract

The temporal profiles of the backscattered pulse from random media are studied experimentally with femtosecond laser and streak-camera technologies. For a weakly scattering medium, the temporal profile of a backscattered pulse can be described by a simple exponential function. In the strongly scattering regime the temporal profile becomes nonexponential. The attenuation lengths arising from scattering and absorption can be directly determined from an analysis of the temporal profile of the backscattered pulse.
