Abstract

During the last years, laser-induced fluorescence techniques with fiber-optical sensors have been established in remote sensing of various environmental pollutants in different media.^1,2 A sensitive analysis of contaminations in a natural surrounding requires an accurate separation between the fluorescence signal from the background media and the pollutant to be detected. Besides only measuring the fluorescence intensities, a time-resolved recording of the fluorescence at particular observation wavelengths improves the sensitivity of the method considerably, when oil or fuel contaminations should be detected.
