Non-conventional imaging systems for 3D digitization of transparent objects: Shape from polarization in the IR and shape from visible fluorescence induced UV

This paper presents a comparison between recent advances made in the field of non conventionnal imaging techniques for 3D digitization of transparent object. After a large survey, this paper will focus on two recent techniques later called : shape from Visible Fluorescence UV-induced and shape from polarisation in the IR which recently emerged. Results obtained with the technique of Scanning from Heating which, originaly developed in 2008 for the digitization of transparent objects, has sucessfully been modified and applied to the digitization of specular objects.
