Abstract

This paper reports on the development of optically based techniques to detect and identify chemical agents. Detection sensitivity and molecule discrimination are studied. In parallel, efforts are made to develop rugged and compact experimental designs that can be used for field measurements. Laser Induced breakdown spectroscopy (LIBS) is a surface analyzing optical technique investigated to measure sarin like molecules deposited on samples coming from the Parisian subway. On the other hand, Tunable Diode Laser Spectroscopy (TDLS) - Cavity Ring-Down Spectroscopy (CRDS) or Cavity Enhanced Absorption Spectroscopy (CEAS) - is used to measure traces of the industrial toxic hydrogen fluoride gas down to the ppb level. Measurements in laboratory are reported and primary results obtained in a field experiment are described.
