Abstract
In the paper we present a method of optical tomography imaging based on the polarization analysis of the scattered photons. By using the Mueller - Stokes formalism we calculated Mueller matrix elements from measurements of the Stokes vector parameters of the light scattered during the angular scanning procedure. Analysis of the changes in the Mueller matrix elements allows recognizing a position of the objects in high scattering medium. Tests of the polarization optical tomography method were carried out with a narrow laser beam (λ=660nm, Ρ=35mW) illuminating a plastic container with Intralipid - a liquid simulating living tissue. The objects to be recognized were made in form of cylindrical probes introduced into a container filled with a solution of the same Intralipid with different optical density in comparison to a liquid inside the container.
