Abstract:
1. A method for examining optical surface properties, in particular for spatially resolved determination of surface properties including the steps: directing a predetermined radiation at a first predetermined solid angle at an examined surface; and detecting at least a portion of the radiation affected by the examined surface a second predetermined solid angle wherein at least one measured variable, which characterizes at least one predefined property of the radiation affected by the examined surface is captured with spatial resolution; determining at least one statistical parameter over at least a portion of the spatially resolution measured values for characterizing the surface, wherein in determining the at least one statistical parameter, the predetermined radiation can be computed back preferably to a standard light type such as in particular A, B, C, D50, D65, D75, F11, TL84 standard light, and particularly preferably to D65 standard light.
