Title (EN) PASSIVE REMOTE SENSOR OF CHEMICALS
(FR) TELECAPTEUR PASSIF DE PRODUITS CHIMIQUES
Abstract:
(EN) A remote sensor for use as a handheld, mobile or stand-alone sensor has first (12) and second (16) optical paths, light collecting optics, a sample filter (10) assembly positioned in a first optical path (12), a reference filter (14) assembly positioned in a second optical path (16), a detector assembly to detect the filtered light or other radiation, and a detector output comparison device such as a BRD to minimize the effects of common background noise components, differences in light or other radiation source power, and absorption or emission by interfering species.
(FR) L'invention concerne un télécapteur portatif, mobile ou un capteur autonome ayant un premier (12) et un second (16) chemin optique, une optique collectrice de lumière, un ensemble filtre (10) d'échantillon positionné dans le premier chemin optique (12), un ensemble filtre (14) de référence positionné dans le second chemin optique (16), un ensemble détecteur détectant la lumière filtrée et d'autres rayons, et un dispositif de comparaison de signal de sortie du détecteur tel qu'un détecteur radiométrique équilibré (BRD) permettant de réduire au minimum les effets des composantes communes de bruit de fond, les différences de lumière ou d'autres sources d'énergie à rayons, et l'absorption ou l'émission des espèces interférantes.
