Abstract

We introduce a diffusing-wave spectroscopic probe which utilizes light pulses and exploits the phase fluctuations of optically gated photons to eliminate the usual average over photon pathways. The principles are discussed and experimentally demonstrated. In addition to testing several critical elements of the original multiple-light-scattering theories, we have studied diffusion of polystyrene spheres in the high-volume-fraction limit where hydrodynamic interactions are important.
