Abstract

A method and apparatus are described for sensing the nature of a gaseous composition, particularly vehicular emissions over a roadway surface, by: disposing substantially parallel to the surface an optical transmission channel including an optical radiation source at one end and a retro-reflector at the opposite end, which retro-reflector is movable axially of the optical transmission channel substantially parallel to the surface towards and away from the optical radiation source; at a first location of the optical transmission channel, diverting a part of the optical radiation therein towards the surface, and detecting by a Light Detection and Ranging (LIDAR) system the particulate matter in the gaseous composition at the first location; at a second location of the optical transmission channel, diverting another part of the optical radiation in the optical transmission channel towards a retro-reflector fixed with respect to the surface, and detecting by a Fourier Transform Infrared Spectroscopy (FTIS) detector system the gaseous composition at the second location, while moving the movable retro-reflector with respect to the optical radiation source; and processing the outputs of the two detector systems to determine whether either output unduly exceeds a predetermined baseline value.
