Abstract
The invention relates to a method of verifying a scan speed in a laser scanning system. The method includes modulating the laser of the system to form a periodically modulated feature from which the actual scan speed can be read or deduced.
Claims19
A method of verifying a scan speed in a laser scanning system of an apparatus for acting on the surface of articles, the method including:
- modulating a laser of the scanning system while scanning a surface of an article with a beam emitted by the laser to form at least one feature, having a periodic pattern, on the article;
- and
- determining, based on a characteristic of the at least one feature, whether the actual speed at which the scanning takes place corresponds to a speed to which the laser scanning system is set.
A method of verifying scan speed in a laser scanning system, including:
- writing at least one feature on an article using a laser of the system;
- modulating the laser using a gated oscillator, as the at least one feature is being formed, to impart a periodic variation in the at least one feature;
- and
- determining, based on a characteristic of the at least one feature, whether the actual speed at which the laser scanning system scans articles with its laser corresponds to a speed to which the laser scanning system is set.
