Abstract
The present invention is a system for the detection of chemical vapors in the atmosphere based on detecting radiation from the molecules of the vapor. The radiation is induced by energy transmitted from the system at a frequency close to an absorption frequency of the molecules of the vapor to be detected. The system provides a easily used means for the excitation and detection of the vapor by virtue of the common tuning control of the system and the direct detection of radiation at the absorption frequency excited by the transmitted energy.
