Abstract
This paper investigates the behavior of a Faraday-active turbid media under ultrafast optical excitation. As the degree of polarization of early arriving photons is mostly preserved during the first 100 ps after the arrival of the ballistic component, it is addressed the possibility of using the magneto-optical rotation of the light polarization as a tool for tissue characterization. The technique may be useful to determining photon scattering statistics in turbid biological media. The analysis is performed on the basis that photons trapped in multiple scattering events leave the medium with larger induced rotation angles. It was found that the experimental observation of picosecond magneto-optical phenomena in scattering media of biological origin is submitted to constraints in the applied magnetic field intensity and in the statistical parameters of photon scattering in the turbid media.
