Oil spill information exaction by laser fluorescence

It is extremely important to detect oil spills and identify oil source so that it can effectively reduce the hazards of the oil spill, and provide trustworthy basic means to emergency response, incident assessment and identification. Based on the principle of laser-induced fluorescence detection, the extraction of oil spills fluorescent information on sea surface was studied in this paper. Via Ground experiments and sea trials respectively validated the airborne laser fluorescence detection system and proved that the entire system was stable and reliable in selection, integration and running chain. The algorithm of curvelet transform with SVM which took advantage of the oil fluorescence spectral shape characteristics and time characteristics was used in order to identify oil type. Except for a relatively high recognition rate, the algorithm has great advantages in small sample and processing speed. So it is especially appropriate for spectrum acquisition and inversion rapidly and simultaneously.
