摘要：

The temporal profiles of ultrashort laser pulses scattered in random media with different experimental geometries were measured and analyzed by using the photon flux and the photon density predicted by the diffusion theory. The scattered laser pulse profiles detected by an optical fiber inside an infinite random medium are found to be described by the photon density. For a semi-infinite medium, the scattered pulse profile emitted from the surface of the medium can be described by either the photon density or the photon flux. These results can be consistently explained by the diffuse intensity (radiance) of transport theory.
