 Process Control

Non-contact ultrasound sensing up to 1 MHz
The optical microphone enables true non-contact surveillance of industrial processes and machines. It does not require solid or liquid coupling, nor does it rely on direct optical access to vibrating surfaces. 

Clear signals, no background
High frequency acoustic emissions typically travel only a few tens of centimeters in air. Thus, the optical microphone listens directly to processes and machines, while background noise from the environment is strongly suppressed. 

Intelligent in-line monitoring
Acoustic signals feature a slim data stream. This allows the implementation of powerful real-time analysis and machine learning methods.

  • Laser welding: in-line feedback on welding parameters and defect detection
  • Chipping: monitoring tool sharpness
  • Wafer dicing: surveillance of Laser dicing machines
  • Piping and valves: detection of vibrations, identification of cavitation regimes
  • Machining: monitoring health and degradation of machining tools
