The invention relates to a device (1) suitable for controlling a surface (8) of an object (7), notably with respect to raised areas on said surface (8). The device (1) comprises a light source (2, 3) for generating a light beam (5, 6) directed towards the surface as well as a light sensor (4) for detecting light scattered by a raised area on the surface (8). The light beam (5, 6) generated by the light source (2, 3) is configured so as to scan the surface (8) in such a way that the raised area on the surface scatters the light beam (5, 6). If there is no raised area the light beam (5, 6) undergoes ideally no, or else only slight, changes. The light sensor (4) is arranged in such a way that at least part of the scattered light can be detected. In this manner it is possible to detect, for example, impurities on uneven or structured surfaces.
