Goniometric measurement of the phase function of different fat emulsions

Fat emulsions like Intralipid are frequently used in research of light propagation in turbid media as tissue phantoms. We investigated the phase functions of different major brands and concentrations (10% and 20%) of these fat emulsions at 633nm and 543nm. A theoretical phase function for fat emulsions was calculated using Mie theory. Only small differences of the phase function of the investigated fat emulsions were found.
