水面溢油在反射光波的过程中,将表现出与自身性质密切相关的特征偏振。因此,对水面溢油的多角度多波段偏振探测成为水体污染遥感监测的一种新手段。本文以汽油、柴油、摩托车机油和大豆油作为水面油污实验样品,应用多角度光谱偏振测量仪实测了不同溢油污染水体的多角度多波段偏振特性数据,探讨了不同溢油污染水体的偏振特性与观测方位角、光源入射角、观测天顶角以及探测波段等影响因素的变化规律,以便为水面溢油污染偏振遥感的研究提供科学依据。
In the process of reflecting light waves, the surface oil spill will show the characteristic polarization closely related to its own properties. Therefore, multi-angle multi-band polarization detection of surface oil spill becomes a new method of water pollution remote sensing monitoring. In this paper, gasoline, diesel, motorbike oil and soybean oil were used as experimental samples of oil surface pollution. Multi-angle spectral polarimeter was used to measure multi-angle multi-band polarization characteristics of different oil spill polluted water bodies. The polarization of water polluted by different oil spills Characteristics and azimuth of observation, the angle of light source, the observation zenith angle and the detection band and so on, in order to provide a scientific basis for the research on the polarization remote sensing of surface oil pollution.
