Abstract: A method to image tissue phantoms using optical technology is demonstrated. The proposed method is based on polarization discrimination. This paper presents both experimental and Monte Carlo based simulation results for the backscattered images of a diffuse reflector object at varying depths illuminated by a linear polarized light beam. The numerical model is validated by experimental measurements using a tissue phantom consisting of 2.02 m diameter polystyrene spheres suspended in deionised water. In this work, the problem related to scattering of light is solved by image-processing means. Results indicate that the proposed method improves the contrast of the subsurface tissue images up to a depth of 1 cm.
