Spectral and time-resolved measurements of pollutants on water surface by an XeCl laser fluorosensor

An excimer-laser-based Lidar fluorosensor, designed for operation from a mobile station, has been assembled at the ENEA Centre in Frascati, and laboratory measurements on different samples have been performed both with spectral and time resolution. A low divergence, high- power XeCl laser has been used for excitation of typical chemical and biological materials polluting water surfaces. Results were obtained on thin films of oils most frequently found in the Mediterranean sea. A rough correlation has been found connecting the average oil density with both the overall visible fluorescence yield as well as the time decay constants.© (1991) COPYRIGHT SPIE--The International Society for Optical Engineering.
