Time dynamics of photon migration in semiopaque random media.
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 degrees 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.
