摘要:

利用二向光度计实测了4个物候期杨树单叶的偏振反射比与二向反射比数据,并对此数据进行了分析,得出了杨树单叶的偏振反射特征与二向反射特征之间的关系及其对物候变化的响应,为偏振光遥感、多角度遥感的深入研究与应用提供了依据,并且对森林遥感也做出了一种新的尝试.

Abstract:

Polarized reflectance and bi-directional reflectance of poplar tree leaves in northeast of China are collected with bi-directional reflectance detection instrument in the lab. Analysis on the relationship between polarized and bi-directional reflectance is done. It is found that bi-directional reflectance is approximately half of the summation of maximum and minimum polarized reflectance. It is also found that the relationship between polarized and bi-directional reflectance have a direct relation to the sensor’s viewing geometry. This study can provide the theoretical basis for further research on the relationship between polarized and bi-directional reflectance for remote sensing.

Key words: polarized light, polarized reflectance, bi-directional reflectance, poplar tree leave
