摘要：
It is shown that the widest differences in the values and angular distributions of the polarization characteristics of the radiation reflected from the leaves of different kinds of plants are observed when a leaf is illuminated at an angle of 55° by He–Ne laser radiation (λ = 0.63 μm) linearly polarized in the plane of incidence. It has been found that the radiation reflected from a leaf becomes elliptically polarized at observation angles of 55° ± 10°. The ellipticity of the radiation reflected from a leaf depends on the thickness of the leaf plate and the position of the top or undersurface of the leaf relative to the direction of illumination.
