Abstract

Battelle has developed a multispectral LIDAR(Llght Detection And Ranging) for the accurate identification and quantification of numerous gaseous pollutants within a range of a few kilometers in the troposphere. This instrument is using the multispectral differential absorption technique (rapid examination of the atmospheric transmission on several different wavelengths). The main components of this DIAL (DIfferential Absorption Lidar) are a CO2 laser operating in the 9 - 11 μm region with a maximum repetition rate of 300 Hz together with a rapid tuning device forming the transmitter and a conventional 8"-Newtonian telescope with a LN-cooled HgCdTe-detector as the receiver. The whole LIDAR instrument is fully controlled by a 16 bit microprocessor system (68000 CPU). The rapid tuning unit allows to emitt pulse pairs of different wavelengths within 3 ms, and to probe up to 10 wavelength pairs within one second.
