Title
(EN) DUAL WAVELENGTH DETECTOR
(FR) DÉTECTEUR À DOUBLE LONGUEUR D'ONDE
Abstract
(EN)
A control system of a detection apparatus for monitoring a condition of an area, the control system including at least one light source operable to selectively emit at least one of a first light having a first wavelength and a second light having a second wavelength. At least one light sensing device is operable to measure a refracted portion of the first light and measure a refracted portion of the second light to determine a type of particle present within the area.
(FR)
L'invention concerne un système de commande d'un appareil de détection permettant de surveiller un état d'une zone, le système de commande comprenant au moins une source de lumière utilisable pour émettre sélectivement au moins une première lumière présentant une première longueur d'onde et une seconde lumière présentant une seconde longueur d'onde. Au moins un dispositif de détection de lumière peut être utilisé pour mesurer une partie réfractée de la première lumière et mesurer une partie réfractée de la seconde lumière pour déterminer un type de particule présent à l'intérieur de la zone.
