Resolution limits for imaging through turbid media with diffuse light

For the achievable resolution for imaging through a turbid medium with multiply scattered light in the diffusion limit, the authors present analytic expressions. The spatial resolution R (the half-width of the point-spread function) scales with thickness d of the sample as R identical with (0.2 plus or minus 0.04)d over 10 order of magnitude in input intensity and transport length are found for detectable levels of light. In good agreement with the calculations are the experiments with a time-gated stimulated Raman amplifier.
