Abstract

La présente invention concerne un dispositif de balayage destiné à détecter un temps de descente de la lumière émise par un matériau luminescent, comportant une unité de commande destinée à adapter le courant d'attaque, ou la valeur de la tension d'attaque, alimenter sa source de lumière pour adapter en conséquence l'intensité de la lumière d'excitation délivrée au matériau luminescent de sorte que son capteur de lumière à haute sensibilité peut mesurer de manière fiable la lumière de luminescence émise en réponse à la lumière d'excitation, et déterminer ainsi avec précision une valeur de temps de descente correspondante.
