Use of polarimetric imaging of emissive objects

This paper describes the use of polarization information to estimate the shape of emissive objects in the field of nonconventional imaging techniques for 3D digitization. Using “Shape from Polarization” method which is applied in the far infrared for transparent object and in the near infrared for the molten metal. Our study shows that by studying the state of polarization of the emitted radiation from the object, normal of the surface can be determined and subsequently the 3D shape.
