摘要
海上溢油污染严重危害着海洋生态环境,为了能够及时了解某一水域的溢油污染程度以及溢油的种类,提出了差分偏振傅里叶变换红外(FTIR)光谱法遥感水面溢油。通过获取分析目标在水平和垂直两个偏振方向的偏振强度差谱,对水面油膜实现了直接探测,并且通过分析差分偏振FTIR光谱中的光谱特征,可以识别水面溢油的种类,弥补了传统热红外遥感探测水面溢油污染的局限性。对差分偏振FTIR光谱探测水面溢油的理论模型进行了分析,并对水面SF96油膜的差分偏振光谱探测分别做了室外实验和理论模拟,实验结果与理论模拟结果有较好的相关性。
Marine oil spill is harmful to the ocean environment.In order to find out the extent of pollution and identify the oil contaminants,an approach for the passive detection of the marine oil spill by differential polarization FTIR spectrometry was proposed.It could detect the marine oil spill directly by obtaining and analyzing the subtracted spectrum of horizontal and vertical polarization intensity spectrum,and it also could identify oil spill by analyzing the spectral characteristic of differential polarization FTIR spectrum.So it well overcame the shortage of traditional thermal remote sensing on detecting marine oil spill.The radiance model of differential polarization FTIR spectrometry was analyzed.The experiment and simulation of detection of SF96 film on water by this method were presented respectively.The experimental result agrees well with the simulation result.
