Abstract: This paper presents a vision system for the in-line monitoring of laser welding. The system is based on a coaxial optical setup purposely chosen to guarantee robust detection of the joints ...

During femtosecond laser fabrication, photons are mainly absorbed by electrons, and the subsequent energy transfer from electrons to ions is of picosecond order. Hence, lattice motion is negligible ...

Whether you're mounting fixtures, installing shelving, or hanging artwork in your home, it's critical to ensure the item is perfectly level. While traditional bubble levels are useful for quick checks ...

Abstract: Laser vision-based welding seam tracking has become the key technology to realize intelligent robotic welding, and extracting the feature point of welding seam is an essential step. Aiming ...
