| 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. |
