Abstract

L'invention concerne un système de mesure de la colorimétrie d'objets comprenant une source d'éclairement (SO), un dispositif de détection (CA) fournissant des signaux électriques représentant l'image de la ou des dents éclairées. La source d'éclairement comporte au moins trois diodes électroluminescentes (DLl à DL3) émettant des faisceaux lumineux de longueurs d'onde différentes et commandées séquentiellement. Une unité centrale (UC) reçoit, du dispositif de détection (CA), à chaque éclairement de l'objet, l'image de la lumière réfléchie et reçue par le dispositif de détection. L'unité de traitement calcule, pour chaque image, le niveau de chaque couleur et détermine, pour différents points, des coordonnées colorimétriques standards. Applications: Systèmes de mesure de la couleur de dents.
