Abstract

Un dispositif portable pour détecter la présence de matières dangereuses comprend une source de lumière pulsée ou modulée dans le temps et un objectif pouvant être balayé à la surface dun échantillon pour projeter de la lumière de la source de lumière sur une succession de points à la surface de léchantillon. Un spectromètre effectue une analyse spectrale de la fluorescence induite pour créer un premier jeu de données définissant un premier vecteur en fonction de la longueur donde. Un détecteur temporel pour mesurer la décroissance temporelle de la fluorescence induite collectée simultanément crée un deuxième ensemble de données définissant un deuxième vecteur en fonction du temps. Un ordinateur identifie un matériau dangereux en effectuant une analyse multivariée indépendante sur les premier et second vecteurs, lobjectif étant balayé sur la surface de léchantillon à laide de modèles de signaux fluorescents pour les matériaux dangereux dans les domaines spectral et temporel.
