Time-domain transmittance imaging in turbid media using an intensified CCD camera

A new instrumentation based on an intensified CCD camera with picosecond time resolution has been developed for optical imaging in turbid media. Scattering inclusions in a homogeneous sample have been detected by fitting the experimental data with a theoretical expression derived from the random walk theory, while absorption inclusions have been localized using time-gated images taken at suitable delays with respect to the expected arrival time of non-scattered photons.
