Without appropriate instruments, human eyes cannot effectively sense the polarization of light. However, it is well known that the eyes of certain animal species are sensitive to light's polarization. Motivated and inspired by hypotheses about the polarization sensitivity of the visual systems of such animals, our research group has been studying and developing an imaging methodology based on "polarization-difference" signals. We have shown that our man-made polarization-difference imaging (PDI) technique can, under certain circumstances, substantially improve contrast and enhance visibility of targets in scattering media. In this talk, a review of our work in the area of biologically inspired PDI will be given and some of our recent results in PDI of objects will be presented and discussed.
