Paper Abstract

A mobile system for the remote measurement of polluting gases such as NO2, SO2 and HC1 has been designed and tested. The detection is based on differential absorption and scattering of infrared radiation. The essential components of the system are a deuterium fluoride laser operated in multiline mode, a 0.6 meter diameter receiver optics, monochromator, and cooled multielement detector array for the simultaneous detection of light backscattered at different frequencies. Range-sensitivity adjustment is optimized using geometrical signal compression techniques. For maximum mobility and versatility the system is mounted in a standard 20 foot container. Design characteristics and special features of the system are reported, ancillary research and development work is described, and applications are proposed.
