Abstract

Dispositif tenu dans la main, pour mesures du facteur de réflexion par infrarouges d'échantillons (M), en vue de l'identification des matériaux constituant lesdits échantillons, qui est une unité portable autonome placée dans un boîtier (10) tenu dans la main. Ledit boîtier (10) comporte une fenêtre (15) et un système optique sur une console (100) adjacente à la fenêtre (15) si bien que ledit système optique est aligné avec l'échantillon (M) lorsque ledit dispositif est placé directement contre l'échantillon (M). Ledit système optique comporte une source (110) de lumière IR à large bande qui brille sur un filtre accordable acousto-optique (120) qui fait passer de la lumière IR à bande étroite avec une fréquence de balayage; une lentille (130) qui focalise les infrarouges à travers la fenêtre (15) sur l'échantillon (M); et un détecteur de réflexion (140) aligné avec la fenêtre (15) du boîtier (10) pour détecter la lumière réfléchie. Un ordinateur (202) qui peut être monté dans le boîtier (10) compare le spectre de réflexion détecté avec des spectres de données d'échantillons stockées et identifie le matériau (M) ou les constituants du matériau (M) et leurs proportions.
