Abstract:
1. A device for examining the optical properties of a surface to be examined made up of a plurality of individual pigments, the device comprising: at least one first radiation means emitting collimated radiation to the surface to be examined at least at a first predetermined spatial angle; at least one first detector means for capturing the radiation emitted to and reflected back from the surface wherein said detector means comprises an image-capturing component configured for allowing a local resolution of detected radiation and is positioned at least at a second predetermined spatial angle relative to said surface, said local resolution enabling examination of the individual points of said radiation detected by said detector means and thereby the examination of the individual pigments and the effects resulting therefrom; at least one further radiation means emitting non-collimated or diffused radiation simultaneously at a plurality of third spatial angles to the surface to be examined; wherein said first, second and third predetermined spatial angles are a tuple of a first spatial subangle and a second spatial subangle; wherein at least one spatial angle at which said radiation means and/or said detector means are positioned, is variable; and wherein the radiation means and the detector means are positioned in a substantially closed volume space which exhibits light-reflecting properties.
