| 摘 要： | 以长春市3个农业灌区水库的水体为实验样本,应用二向反射光度计实测了不同水体在2π空间的多角度偏振反射光谱数据,从探测方位角、光线入射角、探测天顶角、偏振角、波段等方面对所测水体的偏振反射数据进行了初步分析与研究。结果表明:偏振特性是水体的一个固有特征,不仅对污染水体物理性质的测试做出了新尝试,而且为未来污染水体的偏振光遥感研究提供了科学依据。

| Abstract: | In the course of light reflection,light refraction,light absorption and light scattering,not only its intensity but also its polarized state are changed,so the polarized state,a kind of information,can be used in the remote sensing. Water polarized reflectance data from the three reservoirs in Changchun city were collected with a kind of bi-directional reflectance detection instrument.The specialties of this instrument lie in its ability to measure the polarized reflectance of targets at various zenith viewing angles,incidence light zenith angles and azimuth angles with band A(630~690nm)and band B(760~1100nm).Hence,the analysis,according those characteristics,listed above is done.It is found that the polarized phenomena are an important characteristic of water. This study on polarized reflectance of water not only helps to find a new way for polluted water detection,but also provides a theoretical basis for the further research on polluted water polarized light remote sensing. |
