|Title:||Submillimeter and THz Detection of Chemical-Warfare Agents in Air|
|Published:||December 31, 2004|
|Abstract:||Experimental measurements and theoretical calculations were performed to assess the potential for using continuous-wave submillimeter and THz (far-infrared) linear-absorption spectroscopies to detect chemical-warfare agents in air at ambient temperatures and pressures. The experimental studies used three different instruments: a far-infrared, Fourier-transform, polarizing interferometer; a frequency-stabilized, backward-wave oscillator (BWO); and a near-infrared, laser-pumped, THz photomixer. The sensors were evaluated on dimethyl methyl phosphonate (DMMP, C3H9O3P), a common simulant for nerve agents. Recommendations are provided for improving submillimeter and far-infrared methods for the detection of chemical-warfare agents.|
