水面溢油污染的多角度多波段偏振特性研究

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。

Multi-angle and multi-band polarimetric characteristic of spilled oil pollution on water surface

In the course of reflecting light-wave,the spilled oil on water surface will cause the characteristic polarization which is related to the nature of itself.Thus,the detection of the multi-angle and multi-band polarization information for the polluted water by spill oil has become a new monitoring method of remote sense.In this paper,four kinds of oils,gasoline,diesel oil,motorcycle oil and soybean oil,were regarded as the experimental samples on the polluted water.The multi-angle spectral polarimetric instrument was used to obtain the multi-angle and multi-band polarimetric characteristic data on different oil-spilled water.The change rules between the polarimetric characteristic with different affecting factors,such as observation azimuth,incidence angle of the light source,observation zenith angle as well as detection waveband,were discussed.So it can provide the scientific basis for the research on polarization remote sensing on the polluted water by spilled oil.
