dc.description.abstract-translatedWe present an experimental setup to capture photon distributions from a liquid scattering medium and to reconstruct the flux density throughout the medium. The capture mechanism moves an occluder through the medium, which is illuminated by a laser. For each position of the occluder, the exiting light intensity is recorded at selected positions on the boundary of the medium; this produces a measured distribution of intensities blocked by the occluder. The differences between blocked and unblocked intensities are used to solve for sets of photon paths that match the observed exiting light intensity. From these photon paths, we calculate the photon distribution within the medium. This work is validated with experiments using two occluder sizes in different concentrations of milk-water solutions, as well as different incoming and outgoing light poses.en
