A mobile CO{sub 2}-lidar system for the monitoring of hazardous trace gases in industrial areas
- Kayser-Threde GmbH, Muenchen (Germany)
A compact CO{sub 2}-lidar system for the detection of atmospheric pollutants is operating in the mid infrared fingerprint region of organic molecules. The detection limits are set by the system stability and the influence of the atmosphere on the return signal of the lidar. Absorption coefficients of specific gases were measured and compared to the literature. In a first step a comparison of the measurement results in the laboratory with those of a FTIR spectrometer was carried out. The FTIR spectrometer, compared to the lidar system, offers the advantage of the wide coverage of the spectrum (2--15 {micro}m), but the usable range is restricted to a maximum distance of about 500m. The lidar-system can be used for distances of up to 5 km, but is limited on a number of discrete wavelengths.
