Abstract

The use of the polarization of light as a parameter to discriminate against multiple-scattered light for transillumination imaging through random scattering media is examined. Time-resolved two-dimensional images of submillimeter test bars immersed in 5-cm-thick Intralipid solutions with different micelle dilutions were measured for two orthogonal polarizations (parallel and perpendicular) of light emerging from the turbid medium by using a picosecond Kerr–Fourier (KF) imaging system. The measured contrast and intensity of parallel-polarized KF shadowgrams decreased as the concentration of the scattering medium was increased, whereas the behavior of the perpendicular-polarized KF shadowgrams varied in an opposite matter to the micelle concentration.
