Procedure for the production of a structured surface on an object

摘要

In the process, the total surface of the structured surface is divided into sub-areas (1, 2, 3....,(n) a periodic structure with a structural period A(d) is divided and formed there with laser radiation, so that from one observation position (P) several sub-areas (1, 2, 3).... Yeah.n),at different intervals and angles for the observation position (P) discreetly arranged to each other, an image with the same colour impression with the same wavelength l is detectable or recognizable at a radiation of the structured surface with white light. The structural period A(d) of the individual sub-areas (1, 2, 3,....,(n) according to the equation:$\mathrm{\Lambda }\left(\text{d}\right)=m\lambda \text{/}(\text{sin}\left(\mathrm{\theta }i\right)-\text{sin}\left(\mathrm{\theta }\text{obs}\left(d\right)\right)$Definitely.
