摘　　要：太阳耀光一直是困扰水质遥感的突出问题。传统的利用光的偏振性剥离太阳耀光的方法只有当太阳光以水的布儒斯特角入射时才能实现,因此该方法在实际应用中受到了极大的限制。通过深入研究光产生偏振现象的物理机理,找到了在任意入射天顶角情况下通过偏振测量去除太阳耀光的方法,并得到了较为满意的实验验证,使得在向多角度偏振遥感中太阳耀斑剥离的实际应用又迈进了一步。Sun glitter is a problem, which has contused the water quantity remote sensing for a long time. Only when me incidence zenith angle is equal to Brewster angle of water, the traditional method of peeling-off sun glitter is valid that is based on the light＇s polarized character. Therefor, this method is extremely restricted in actual application. A new method of sun glitter＇ s elimination through polarized measure has been found and satisfactorily tested. This method can be used at any incidence zenith angle. Then the study on sun glitter＇ s peeling-off of multi-angle polarized remote sensing in actual application is further than ever before.
