Abstract

Some researchers assume that the light reflection from leaves is Lambertian, but I verify that some leaves exist showing no Lambertian reflection. One can measure the indicatrixes of leaves of various woody plant species by the use of a goniophotometer. Minnaert constants can be calculated from these indicatrixes for quantitative evaluation. I discuss why light scattering from leaves does not always obey Lambertian law.
