Abstract

L'invention concerne un dispositif de caractérisation optique d'un corps (2) translucide ou opaque comportant : des moyens d'éclairage (3) comprenant une source lumineuse (S), apte à émettre un flux lumineux en direction du corps (2), un système de détection et d'analyse (4) du flux lumineux transmis et/ou diffusé (φt/d) par le corps (2), des moyens de calibrage (10) du dispositif, comportant un élément optiquement neutre (11) destiné à être positionné à la place du corps (2) dans le trajet lumineux de manière à définir une nouvelle échelle de mesure comprise entre un premier niveau, correspondant à la signature optique de l'élément optiquement neutre (11), et un second niveau, correspondant à la signature optique d'un corps parfaitement opaque. Dispositifs de caractérisation optique.
