Differential absorption lidar CO2 laser system for remote sensing of TATP related gases
A CW tunable 10.6 mu m CO2 laser differential absorption lidar (DIAL) system has been developed, for the first time to our knowledge, for the remote sensing of triacetone triperoxide (TATP) gas vapors, which have strong absorption lines at several wavelengths, including 3.3, 8.3, and 10.6 mu m. The DIAL laser beam was transmitted through an enclosed absorption cell containing TATP or SF6, and backscattered returns were measured from a retroreflector array target at ranges of 5-100m. DIAL sensitivity for the detection of TATP was about 0.5 ng/mu l [52 parts in 10(6)(ppm)] for a 0.3m path. (C) 2009 Optical Society of America
