Abstract

The depolarization of light in diffused medium was studied by observation of temporal profiles of orthogonally polarized components. The time dependence of depolarization of light in diffused medium was simulated by using the Monte Carlo method. The projection data of absorbers hidden in highly scattering medium were taken by the method for detecting photons which preserved initial polarization using a phase modulator. The floor level due to diffused light was significantly suppressed by our method. The reconstructed optical CT image exhibited high spatial resolution in comparison with the image from the projection data taken by a conventional method.
