Research on the polarized characteristics of leaves

The distributions of polarized reflectance from several leaves surfaces are measured by the multi-direction instrument, including corn tender leaf, corn mature leaf, and lilac leaf. The degrees of polarization corresponding to different incident zenith angle and view zenith angle are calculated. Some results can be concluded by comparing the degree of polarization: the degree of polarization will increase with incident zenith angle and view zenith angle. These indicate that non-Lambertian of leaf surface will be distinct with the increasing of incident zenith angle.
