Minnaert constants are calculated from the intensity of the light scattered from the surface of objects. Focused on remote sensing of vegetation on the earth's surface, the light reflected from leaves is measured. A remote sensing simulator is used in an experimental room with a halogen lamp as an optical source and a Wratten gelatin filter No. 25 as a filter. Bidirectional reflectance from two kinds of leaves with different degrees of roughness is measured and their Minnaert constants are obtained by recurrent analysis of the results. The Minnaert constant for a leaf with a smooth surface is larger than 1 (Lambertian surface) and that with a rough surface is smaller than 1.
