摘要

Arrangement for the characterization of irregularities on planes, and transparent surfaces of articles, for example, a cement layer, with the use of a light source with an optical mask for the spatial intensity modulation of the light and a ccd - camera in the region of the emergent light for detecting the data for an evaluation unit, wherein the light source (1) diffused light is generated, which in an angle of incidence (6) of 10 degrees to 40 degrees to the plane and transparent surface (3) of the object is directed, and wherein the article on a carrier (7) is arranged on its surface has image structures (8).
