Laser Induced Fluorescence Spectroscopy for in-situ Detection of Petroleum Contamination

A fiber-optic chemical sensor has been developed using laser induced fluorescence (LIF) to provide high resolution, real-time, in-situ field detection of underground petroleum contamination. Recent experiments using a 308 nm XeCl laser source have shown improved performance, particularly at detectin...

Zusammenfassung:A fiber-optic chemical sensor has been developed using laser induced fluorescence (LIF) to provide high resolution, real-time, in-situ field detection of underground petroleum contamination. Recent experiments using a 308 nm XeCl laser source have shown improved performance, particularly at detecting light molecular weight (i.e. aviation) fuels. Prepared in collaboration with Computer Sciences Corporation, San Diego CA and the University of California, San Diego. This paper was presented at the 1996 XX International Quantum Electronics Conference, Sydney, Australia, 14-19 Jul 96.
