Abstract
We present results of experiments on the transport of light through thin random media. Total transmission and time-resolved propagation measurements were performed using strongly scattering samples of varying thickness $L$. For $L/\ensuremath{\ell}<8$, where $\ensuremath{\ell}$ is the transport mean free path, the observed decay times from the long-time exponential behavior exhibit strong deviations from diffusion theory and radiative transport theory, whereas the total transmission measurements do not. For the thinnest sample $(L/\ensuremath{\ell}\ensuremath{\simeq}2)$ a reduction of the diffusion coefficient with a factor of 2 was observed.
