A liquid phantom for investigating light propagation through layered diffusive media is described. The diffusive medium is an aqueous suspension of calibrated scatterers and absorbers. A thin membrane separates layers with different optical properties. Experiments showed that a material with scattering properties should be used for the membrane to avoid the perturbation due to the guided propagation that occurs through a transparent layer. Examples of measurements on a three-layered medium are reported both in the cw and in the time domain.

Abstract
A liquid phantom for investigating light propagation through layered diffusive media is described. The diffusive medium is an aqueous suspension of calibrated scatterers and absorbers. A thin membrane separates layers with different optical properties. Experiments showed that a material with scattering properties should be used for the membrane to avoid the perturbation due to the guided propagation that occurs through a transparent layer. Examples of measurements on a three-layered medium are reported both in the cw and in the time domain.File in questo prodotto:
