ROTATING POLARIZATION IMAGING IN TURBID MEDIA

It is shown experimentally that one can image an object embedded in a turbid medium by probing the medium with light with a rotating linear polarization. This method permits the ballistic photons to be isolated from the large background of photons that have been multiply scattere d by optically dense anisotropic scatterers. This technique achieves a good signal-to-noise ratio even viith a low-power continuous laser, l eading to images with a diffraction-limited resolution comparable with that obtained in optically homogeneous media.
