Abstract
Il s'agit d'un détecteur de gaz mobile qui comprend un émetteur laser et un analyseur de signaux sur véhicule. Ce véhicule comporte les éléments qui suivent : à l'extérieur, une cellule d'absorption laser; un conduit de lumière raccordant la lumière de l'émetteur laser à l'intérieur de la cellule d'absorption laser; un photodétecteur installé avec la cellule d'absorption laser à l'extérieur du véhicule pour convertir la lumière traversant la cellule d'absorption laser en signaux électriques; et un câble raccordant le photodétecteur à l'analyseur de signaux.
