Paper Abstract

In this paper we present a laser spectroscopy system designed for application in standoff chemical detection. The system is based on a dispersion sensing approach which provides high immunity to amplitude noise and optical power fluctuations. It is well suited for industrial applications (e.g. leak detection) as well as for environmental monitoring (e.g. measuring emissions from distributed sources like wetlands or water reservoirs using single instrument that covers large area with path-integrated detection). A detailed system configuration is presented. Feasibility of standoff gas detection using laser dispersion spectrometer with scattering optical targets is demonstrated.
