Abstract Oil film thickness is an important index for quantitative analysis of sea surface oil spill pollution. Based on the morphological characteristics of the even and uneven thick oil film areas in the sea surface oil spill, the determination method was given based on the signal characteristics of laser-induced fluorescence (LIF) detecting oil film with different thickness, and the thickness evaluation method of the edge of even thick oil film area was proposed. The oil film thickness was estimated according to the fluorescence intensity corresponding to the thickness of the oil film area edge. The thickness change of the even thick oil film edge was observed, and the thickness of the even thick oil film was evaluated by LIF experimental system. The results show that the relative deviation of this method is about ± 10% for the oil film thickness greater than 20 μm.

Key words： metrology oil film thickness oil spill assessment laser-induced fluorescence fluorescence intensity
