摘要
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 ()-1/2. This constitutes the experimental proof for the buildup of long-range intensity correlations in the propagation of classical waves by multiple scattering. © 1990 The American Physical Society.
