Paper Abstract

There are many well-known tomographic methods for the determination of physical quantities in a 2D or 3D space. Most of these quantities are scalar or vectorial. In this paper, a novel method is presented to determine a tensorial quantity in a 3D space: The determination of the 3D stress tensor and of the 3D refractive tensor in photoelastic materials is achieved by applying otpical tensor field tomography. The theory of the projection is described, and the principles of two reconstruction algorithms are explained. The experimental setup is presented, and difficulties in measuring the projections are described. Finally, experimental results are shown.
