| Abstract: | Polarized reflectance and bi-directional reflectance of poplar tree l e aves in northeast of China are collected with bi-directional reflectance detect i on 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 reflectanc e. It is also found that the relationship between polarized and bi-directional r e flectance have a direct relation to the sensor's viewing geometry. This study ca n provide the theoretical basis for further research on the relationship between polarized and bi-directional reflectance for remote sensing. |
