Abstract
The intensity temporal profiles of diffusive light propagation in high ly concentrated (up to volume fraction phi similar to 0.55) dispersion s measured by 100-fs laser pulses showed an increase in transport scat tering mean free path above a critical concentration. This observation confirms the previous theoretical predictions of enhanced transmissio n at high particle concentrations due to correlated scattering. The co rrelation effects are accounted for by incorporating a hard sphere Per cus-Yevick static structure factor into the prediction of transport me an free path. (C) 1998 Optical Society of America.
