The invention relates to a device for detecting and/or recognizing markings, in particular for manual handling, comprising a camera for recording a marking and at least one illumination device for illuminating a marking, characterized in that, for detecting and/or recognizing markings () on/at/in transparent marking carriers (), in particular having reflectively polished surfaces, the at least one illumination device () is arranged at a distance from the optical axis (A) of the camera () in such a way that the light reflection () generated by the at least one illumination device () at the surface of the transparent marking carrier () is arranged at least alongside the marking represented in the camera image, preferably outside the detection region of the camera (). The invention furthermore relates to a method in which, for detecting and/or recognizing markings () on/at/in transparent marking carriers (), in particular having reflectively polished surfaces, a marking is illuminated by at least one illumination device () spaced apart from the optical axis (A) of the camera () in such a way that the marking appears in inverted fashion in the camera image, in particular as a bright marking on a dark background, and the light reflection () generated by the at least one illumination device () at the surface of the transparent marking carrier () is arranged at least alongside the marking represented in the camera image, preferably outside the detection region of the camera ().

Device and method for detecting and/or recognizing markings in/at/on transparent marking carriers

The invention relates to a process for the marking of an object surface, wherein there is arranged in contact with, or a distance away from the object surface a carrier element, featuring on its side facing the object surface at least one metal coating embedded in other layers, whereby the layers in particular form a Low-E coating system and whereby a laser beam is directed onto the coating system and by reason of the laser irradiation material is transferred from the coating system onto the object surface to be marked, adhering thereto as a matrix with metallic nano-particles, whereby the matrix is formed of the substances originally present in the layers of the coating system. The invention furthermore relates to an object with an object surface marked according to this process.
