Field Tests of the Laser Interrogation of Surface Agents (Lisa) System for On-the-Move Standoff Sensing of Chemical Agents

Abstract : Laser Interrogation of Surface Agents (LISA) is a new technique based on short-range Raman sensing that provides standoff detection and identification of surface-deposited chemical agents. ITT Industries, Advanced Engineering and Sciences Division is currently developing the LISA technology under a cost-sharing arrangement with the U.S. Army Soldier and Biological Chemical Command (SBCCOM) for incorporation on the Army's future reconnaissance vehicles. We will discuss the field engineered prototype LISA-Recon system, designed to demonstrate single-shot on-the-move measurements of chemical contaminants at concentration levels below the Army's requirements. Results from laboratory and field tests will be presented. Proper identification of chemical contamination requires an on-board library of high-resolution UV Raman signatures. Laboratory measurements of these Raman spectra are presented in a companion paper.
