Observation of intensity statistics of light transmitted through 3D random media
| Abstract | We experimentally observe the spatial intensity statistics of lighttransmitted through three-dimensional (3D) isotropic scattering media.The intensity distributions measured through layers consisting of zincoxide nanoparticles differ significantly from the usual Rayleighstatistics associated with speckle and instead are in agreement with thepredictions of mesoscopic transport theory, taking into account theknown material parameters of the samples. Consistent with the measuredspatial intensity fluctuations, the total transmission fluctuates. Themagnitude of the fluctuations in the total transmission is smaller thanexpected on the basis of quasi-one-dimensional (1D) transport theory,which indicates that quasi-1D theories cannot fully describe these open3D media. |
