Abstract

We measure the optical properties of turbid media by performing a spatial scan for homogeneous liquid samples and by immersion into a known reference medium for small secondary samples. We demonstrate that both types of measurements have a precision of better than 1% (standard deviation) and an absolute accuracy of better than 3% (mean error). Furthermore we conduct an experiment measuring the absorption and scattering coefficients of a human hand immersed into a reference medium for a changing level of blood oxygenation.
