An object consisting of small inhomogeneities embedded in a highly scattering solution was imaged using measurements of the time-resolved transmitted intensity of picosecond pulses of near-infrared light. Data acquisition involved translating the object in two orthogonal directions across the beam, and recording the temporal distribution of transmitted light at a series of discrete positions. Images were constructed from the total transmitted light, the first four moments of the temporal distribution, and from parameters derived from a comparison of the distribution with an analytical model, based on the diffusion approximation to the radiative transfer theory. The results show that the optical properties along a line-of-sight between source and detector influence some of these characteristics more than others.
