Apparatus mechanism and method for investigating coatings with effect pigments

摘要

The method involves directing radiation on a surface (10) with a wave length range using an irradiation device. A radiation detecting unit records a spatially resolved image of radiation scattered and reflected from the surface. The irradiation device directs radiation on the surface with another wave length range. The image recording unit records another spatially resolved image of the radiation scattered and reflected from the surface. The radiation with former wave length range and the radiation with latter wave length range are aligned on the surface in a temporally displaced manner. An independent claim is also included for an apparatus for testing of optical surface properties of surfaces, particularly coatings with effective pigments.
