Determining Surface Orientations of Transparent Objects Based on Polarization Degrees in Visible and Infrared Wavelength

"Determining surface orientations of transparent objects based on polarization degrees in visible and infrared wavelengths," 1 Techniques for modeling an object through observation are very important i n o b j e c t recognition and virtual reality. A wide variety o f t e c hniques have been developed for modeling objects with opaque surfaces, whereas less attention has been paid to objects with transparent surfaces. A transparent surface has only surface reeectionn it has little body reeection. This paper presents a new method for obtaining surface orientations of transparent surfaces through analysis of the degree of polarization in surface reeection in visible and far infrared wavelengths, respectively. This parameter , the polarization degree of reeected light in the visible wavelength, is used for determining the surface orientation at a surface point. The polarization degree in visible wavelengths provides two solutions, and the proposed method uses the polarization degree in the far infrared wavelength to resolve this ambiguity.
