【摘要】 水面镜面反射会产生太阳耀光,直接影响水体遥感信息的提取和利用。光在与物体相互作用的过程中,不仅其强度会发生变化,而且偏振状态也会发生变化。结合这两种情况,利用偏振反射的变化来消除太阳耀光。从理论上推导了偏振反射消除太阳耀光的可能性,实验测定了自来水和汽油在2π空间中的偏振反射光谱,分析了光线入射角、探测角、探测方位角、偏振角等因子与液体偏振反射比的普适关系。实验证明,当太阳处在一定的天顶角时,通过设置偏振角可以成功的消除太阳耀光的影响。更多还原

【Abstract】 The mirror reflectance of water surface produces the sun glitter,it is unable to draw water body information from the total radiation at all.For the course of light reflection,light refraction,light absorption and light scattering,not only its intensity can be changed,but also its polarized state can be changed,so it is a method to eliminated sun glitter by the change of polarized state.The feasibility of sun glitter’s elimination by polarized was set forth;and the polarized reflectance spectrums of water and gasoline in 2π space were dealt with.The ubiquitous relationships between polarized reflectance spectrum and other influencing factors were measured,these influencing factors include incidence angle,exploration angle,horizontal azimuth and polarized angle.The experiment proves,when the incidence angle is Brewster’s angle,polarized angle can change successful eliminated the sun glitter in multi-angle remote sensing.更多还原
