Abstract
This paper summarizes the results of experiments in developing a method for extracting 3D information and indices of refraction from a scene by means of a pair of polarimetric passive imaging sensors. Each sensor provides Stokes vector at each sensor pixel location, from which, degree and angle of linear polarization are computed. Angle of linear polarization provides the azimuth angle of the surface normal vector. The depression angle of this surface normal vector is obtained in terms of the emitting object's index of refraction. By relating the corresponding surface normal orientation angles at each pixel from the images of the two sensors index of refraction at that pixel can be estimated.
