摘要 激光诱导荧光(LIF)技术是目前较为有效的海面溢油探测技术之一,然而基于该技术的油膜厚度反演算法目前仅适用于薄油膜(≤20μm)。鉴于此,建立了一种基于LIF技术利用油膜荧光信号评估较厚油膜厚度的双波段比值模型,利用油膜荧光光谱的波形特性反演油膜厚度并论证了该算法的适用范围。实验数据得出,当油膜较薄时反演结果误差较大,随着油膜厚度增加误差逐渐降低,当油膜荧光信号趋于饱和时,误差较大且随油膜厚度的增加而快速变大。实验结果表明,该算法可以有效评估200~1400μm范围内的海面溢油油膜的厚度,并可以利用油膜荧光信号的测量相对误差评估该算法的适用范围。

Abstract:Oil spill has become one of the most serious problems of marine pollution, laser-induced fluorescence (LIF) technology is considered to be one of the most effective detection technologies for sea oil spill. At present, based on LIF, the oil film thickness inversion algorithm is only suitable for the thin oil film (≤20μm). In order to detect the thick oil film, a dual-band ratio model is proposed to evaluate the thickness of thick oil film, the wave characteristics of oil film fluorescence spectra are used to invert the thickness and the applicability of the method are given. The method is verified by experiments. When the oil film is thin, the inversion error is large, and it decreases gradually with the increase of the oil film thickness. When the oil film fluorescence signal tends to saturation, the inversion error is large and increases rapidly with the increase of the oil film thickness. The experimental results show that the algorithm can effectively evaluate the thickness of spill film in the range of 200~1400μm on the sea surface, and the relative error of the oil film fluorescence signal can be used to evaluate the applicability of the algorithm.
