摘要
矿物岩石在反射、散射和透射电磁辐射的过程中,表现出与它们自身性质有关的偏振特性。因此,对矿物岩石的多角度偏振信息探测成为岩石定量遥感的一种新手段。偏振反射是伴随目标的二向反射而产生的,在探测目标地物的二向反射的同时,可以通过起偏器获得目标地物偏振态的三维空间分布。本文从多角度偏振遥感机理的角度出发,研究了橄榄岩多角度偏振反射与二向反射之间存在的定量关系并从实验上验证了其二向反射、45度偏振、偏振均值三者在2π空间的相应方位角、天顶角、探测角以及通道上的反射比均相等。
In the process of reflecting, scattering and transmitting electromagnetic wave, mineral rock behaves the polarized characteristics related to the nature of themselves, therefore, the detection of multi-angle polarization information of mineral rock has become a new method of quantitative remote sensing of rocks. For ground objects, the occurrence of bi-directional reflectance always is accompanied with polarized reflectance, so the three-dimensional spatial distribution of polarized reflectance of ground objects can be attained by a polarimeter when detecting their bi-directional reflectance. From the angle of the mechanism of multi-angle polarized remote sensing, this paper studies the quantitative relation between multi-angle polarized reflectance and bi-directional reflectance of peridotite, and by the experimentations proves that the reflectance of bi-directional reflection, polarized reflection of 45 degree and polarized reflection of mean value in the corresponding azimuth angle, zenith angle, detection angle and detection channels in 2π space are equal all.
