This paper briefly discusses the polarizing reflectance characteristics of the simple leaves of several plants. We use the self\|made photometer with A band （630\

6

90nm） and B band （760\

1

100nm） to measure the polarizing reflectance at various viewing angles

incidence angles and azimuth angles. According to the analysis

the reflectance characteristics are related to both plant species sun incidence angle and sensor’s viewing geometry. In short

the corresponding study on polarizing reflectance not only help to plant recognition but also provide the theoretical basis for further researches on the remote sensing of polarized light.
