Goniospectrometric properties of a white standardReflection spectroscopy is one of the fundamental tools in planetary remote sensing. Most of the laboratory work is done in terms of bidirectional reflectance R in the wavelength range of reflected sunlight (250 nm - 2500 nm). Bidirectional reflectance R is defined as the radiance of a surface relative to the radiance of an ideal Lambertian reflector, identically illuminated (radiance coefficient). For quantitative laboratory work the absolute scale of R has to be known. In addition, for many purposes it is necessary to know the dependence of R from phase angle for a large range of geometries. In many cases, this can only be achieved if the goniospectrometric properties of the white standard that is used are known with high precision. For a long time Halon has been used as a white standard by most laboratories. Because Halon is no more available we have now analyzed the goniospectrometric properties of Spectralon SRS-99 with the DLR-goniospectrometer.
