Claims14
A device for forming a two-dimensional or three-dimensional microstructured identification structure in a defined surface region in a surface of a component or product, said device comprising:
- a) a laser device for generating at least one laser beam;
- b) a control device for the variable control and setting of the laser beam or beams;
- c) hardware and software for generating control commands for the control device from at least pattern data of a certain two-dimensional or three-dimensional pattern (M) and coding data for controlling the laser beams in such a way that a two-dimensional or three-dimensional microstructured identification structure can accordingly be formed in the defined surface region, which represents a superposition of the two-dimensional or three-dimensional pattern (M) with the coding data.
A decoding device comprising an optical detection unit for reading the coding from a two-dimensional or three-dimensional microstructured identification structure generated using the device in a defined surface region in a surface of a component.
A component, which has a two-dimensional or three-dimensional microstructured identification structure, which has a superposition of a two-dimensional or three-dimensional pattern (M) with a coding which can be registered only by means of a suitable decoding device, in a surface region of a surface of the component.
