Process and Beam Control

  • Monitoring, control and closed-loop control of laser manufacturing processes for many laser applications at a vast variety of wavelengths
  • Process monitoring using spatially and temporally high resolution camera systems and fast hardware-based real time image processing
  • Feasibility studies of process monitoring and control
  • Integration of process monitoring and control in existing manufacturing facilities
  • Development of customized sensors such as simultaneous TCP and seam tracking during laser welding or position and kinematics measurements at remote and robotic applications
  • Construction of networked multi-sensor systems, e. g. for computer-aided production data acquisition and multi-parameter closed-loop control
