Abstract
The invention relates to a method and a device (100) for forming a two-dimensional or three-dimensional micro-structured identification structure (200) in a defined surface region (12) in a surface (11) of a component (10) or product.
Claims15
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 the two-dimensional or three-dimensional microstructured identification structure can accordingly be formed in the defined surface region, wherein the coding data is integrated within the two-dimensional or three-dimensional pattern (M) in a manner which is imperceptible to the human eye.
