Fluctuations of scattered waves: going beyond the ensemble average
Abbreviated Journal Title
WEAK-LOCALIZATION; RANDOM-MEDIA; PROPAGATION; Optics
The interaction between coherent waves and random media is a complicated, deterministic process that is usually examined upon ensemble averaging. The result of one realization of the interaction process depends on the specific disorder present in an experimentally controllable interaction volume. We show that this randomness can be quantified and structural information not apparent in the ensemble average can be obtained. We use the information entropy as a viable measure of randomness and we demonstrate that its rate of change provides means for discriminating between media with identical mean characteristics.
