Abstract

The temporal behavior of femtosecond laser pulses propagating and scattering in random media was studied using an optical fiber probe and a streak camera. Information on the temporal profile of laser pulse scattering at 90° in semiopaque media was analyzed. Apparent ballistic transport was observed for both single and multiple scattering regimes. A phantom (hidden foreign object) was identified in a semiopaque environment using time resolved techniques with a total optical density of ~3.
