Abstract
L'invention porte sur un procédé et sur un appareil pour détecter la nature d'une composition gazeuse, particulièrement des émissions de véhicule sur une surface de chaussée, en : disposant de manière sensiblement parallèle à la surface un canal de transmission optique comprenant une source de rayonnement optique au niveau d'une extrémité et un catadioptre au niveau de l'extrémité opposée, lequel catadioptre est mobile de manière axiale sur le canal de transmission optique sensiblement parallèlement à la surface en direction de et de façon à s'éloigner de la source de rayonnement optique; au niveau d'une première position du canal de transmission optique, en détournant une partie du rayonnement optique dans celui-ci vers la surface, et en détectant au moyen d'un système de détection et télémétrie par la lumière (LIDAR) la matière particulaire dans la composition gazeuse au niveau de la première position; au niveau d'une seconde position du canal de transmission optique, en détournant une autre partie du rayonnement optique dans le canal de transmission optique vers un catadioptre fixe par rapport à la surface, et en détectant au moyen d'un système de détection de spectroscopie infrarouge à transformée de Fourier (FTIS) la composition gazeuse au niveau de la seconde position, tout en déplaçant la catadioptre mobile par rapport à la source de rayonnement optique; et en traitant les sorties des deux systèmes de détection pour déterminer si l'une ou l'autre des sorties dépasse excessivement une valeur de référence prédéterminée.
