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.
