Patent ID: 7433055

Claim:
A device for examining the optical properties of surfaces comprising: at least one first radiation means—emitting radiation at a first predetermined spatial angle to a surface to be examined; at least one first detector means for capturing the radiation emitted to and reflected back from the surface wherein said first detector means comprises an image-capturing component, allowing a local resolution of detected radiation, wherein said first detector means is positioned at a second predetermined spatial angle relative to said surface; at least one second radiation means which emits radiation to the surface to be examined, said at least one first and second radiation means being arranged at different spatial angles relative to the surface to be examined for emitting radiation onto the surface; and at least one second detector means which detects radiation emitted to and reflected back from the surface to be examined, wherein said second detector means is arranged at a third predetermined spatial angle and does not permit local resolution; wherein said first, second and third spatial angles are each defined by a tupel of a first spatial subangle and a second spatial subangle each indicating a projection angle relative to a surface perpendicular to the surface to be examined; and wherein said tupel of said second spatial angle is (0°, 0°), such that said second spatial angle is perpendicular above the surface to be examined.
