Observation of anisotropic diffusion of light in compacted granular porous materials

Alerstam, Erik LU and Svensson, Tomas LU (2012) In Physical Review E (Statistical, Nonlinear, and Soft Matter Physics) 85(4).
Abstract
By analyzing spatio-temporal characteristics of short optical pulses diffusively transmitted through compacted granular materials, we reveal that powder compaction can give rise to strongly anisotropic light diffusion. Our disclosure represents a revision of the understanding of optics of powder compacts. Routes to material characterization and investigation of compression-induced structural anisotropy are opened, and the falsification of isotropic models have implications for quantitative spectroscopy of powder compacts (e.g., pharmaceutical tablets).
