Abstract

In this paper is presented an IR imaging technique allowing one to retrieve quantitative concentration and temperature maps with relatively fast acquisition times of samples evolving in time. A model study is realized based on the drying of a drop of colloidal dispersion in confined geometry and quantitative maps of colloid volume fraction and temperature everywhere in the dorp are retrieved. Finally, a secondary technique of IR tomography is presented to extend the setup sensitivity to the thickness of the sample and 3D tomographs of both thermal emissivity and IR absorbance of a silica gel are constructed numerically.
