Infrared tomography: towards a novel methodology to investigate the volumetric radiative properties of heterogeneous materials

Abstract

Knowledge of the volumetric radiative properties of heterogeneous semi-transparent materials is of crucial interest to accurately quantify the propagation of radiative energy carried through them. When the materials exhibit a complex texture, the determination of their radiative properties remains tricky. Experimental and/or numerical methodologies aiming to finely retrieve the spatial dependence of these properties are at their first step of development. The research proposed in this paper uses optical tomography and specific numerical approaches to solve the inherent inverse problem to solve this issue.
