Abstract

Express-monitoring of mineral oil spilled into water is one of the most important issues of environment protection. Remote diagnostics of mineral oil on water surface necessarily includes fast mapping of the spill, oil type recognition, and estimation of thickness of oil spilled on water surface. Since very thin oil films spread on water surface affect the character of aquatic and atmospheric processes it becomes very actual to measure film thickness within the micrometer accuracy. Today the only sensor which has the ability to positively identify and quantify oil films is the laser fluorosensor. Currently the LIDAR techniques for oil spill monitoring are based on detection of laser induced oil fluorescence and backscattered water Raman signal. The technique of water Raman suppression by an oil spill is used for oil film thickness measurement and evaluation of the total oil volume spread on water surface.
