Investigation on principle of polarization-difference imaging in turbid conditions

Abstract We investigate the principle of polarization-difference imaging (PDI) of objects in optically scattering environments. The work is performed by both Marius’s law and Mueller–Stokes formalism, and is further demonstrated by simulation. The results show that the object image is obtained based on the difference in polarization direction between the scatter noise and the target signal, and imaging performance is closely related to the choice of polarization analyzer axis. In addition, this study illustrates the potential of Stoke vector for promoting application of PDI system in the real world scene.
