Laser Monopulse Fluorescent Method of Oil Pollution Monitoring

The paper focuses on possible applications of laser monopulse fluorescent method in the field of remote oil pipeline leaks sensing and detection of land oil pollution. The research shows that application of the method of quasi-expansions detection for analysis of fluorescent signals reflected from the land surface makes it possible to reproduce the spatial distribution of effective quantum yield of probed surface fluorescence in the sight of lidar receiving system. With the measurement error at the level of 1.5 % the error of output data is 20...30 %. The analysis of spatial distribution stated above allows us to locate the surface areas with the highest level of laser-induced fluorescence. The application of swarm optimization method for quasi-expansions detection instead of the method of complete enumeration reduces the calculation time approximately ten times. The processing of laser-inducted fluorescence in several spectrum ranges permits to detect the oil-polluted land areas
