Abstract
We report time-resolved measurements of the statistics of pulsed transmission through quasi-one-dimensional dielectric media with static disorder. The normalized intensity correlation function with displacement and polarization rotation for an incident pulse of linewidth at delay time t is a function only of the field correlation function, which is identical to that found for steady-state excitation, and of , the residual degree of intensity correlation at points at which the field correlation function vanishes. The dynamic probability distribution of normalized intensity depends only upon . Steady-state statistics are recovered in the limit ->0, in which is the steady-state degree of correlation.
