| 摘 要： | 为了更好地进行水体油污染监测,首先简要介绍了多角度偏振探测技术,然后着重分析了水体油污染目标的偏振特性,同时从目标地物反射光谱的偏振探测机理出发,讨论了它们偏振光谱的空间特征,并总结出3条普适规律.结果显示:偏振光谱信息与强度辐射光谱信息相比,目标地物间反射光谱的微小差异得到了增强,且在大角度入射时,增强效果更为明显....

| Abstract: | The technique of multi-angle polarization detection is described briefly in this paper.Based on experiments,the authors analyzed in detail polarized characteristics of the oil pollution object.The spatial characteristics of the spectrum of polarized light are discussed from the mechanism of polarization detection,and three universal laws are summarized.In comparison with intensity spectrum,small discrepancy of the object is enhanced,especially in the case of polarized light incidence at a large angle.Multi-... |
