Title (EN) SYSTEM AND METHOD FOR DETECTING GASOCHROMIC EMISSION SPECTRA
(FR) SYSTÈME ET PROCÉDÉ DE DÉTECTION DE SPECTRES D'ÉMISSION GAZOCHROME
Abstract:
(EN) A detection method and system includes applying a gas to an article, the article including a gasochromic material capable of emitting a radiation emission spectrum in the presence of the gas, the article further including a first absorptive material capable of absorbing radiation in a first narrow bandwidth within the emission spectrum to produce a first narrow bandwidth absorption line in the emission spectrum, irradiating the article in the presence of the gas; and detecting the emission spectrum having the first narrow bandwidth absorption line.
(FR) La présente invention concerne un procédé et un système de détection comprenant l'application d'un gaz à un article, l'article comprenant un matériau gazochrome pouvant émettre un spectre d'émission de rayonnement en présence du gaz, l'article comprenant en outre un premier matériau absorbant pouvant absorber un rayonnement dans une première largeur de bande étroite dans le spectre d'émission pour produire une première ligne d'absorption à largeur de bande étroite dans le spectre d'émission, l'exposition de l'article à un rayonnement en présence du gaz et la détection du spectre d'émission comprenant la première ligne d'absorption à largeur de bande étroite.
