Observation of long-range intensity correlation in the transport of coherent light through a random medium
| Abstract | We have measured the correlation in frequency-dependent intensity fluctuations in the total transmission through random dielectric samples, using visible light in a (essentially) plane-wave geometry. The correlation function, of which the width at half maximum is proportional to L−2 (L is the thickness of the sample), decays as (Δω)−1/2. This constitutes the experimental proof for the buildup of long-range intensity correlations in the propagation of classical waves by multiple scattering. |
