Demonstration of Frequency Bandwidth

  • The Optical Microphone is able to detect the entire acoustic frequency bandwidth which is transmitted through air
  • High frequencies often contain significant process-quality information
  • Hence, disturbing background noise (low frequencies) can be separated from process information (high frequencies)

Laser Ultrasound Inspection of Spot-Welded Joints

  • Spot weld characterization with XARION's non-destructive scanning system
  • Single-sided setup using XARION's optical microphone 
  • Robot-based, fully automated, no contact fluid required

XARION's Solution for Non-Destructive Material Testing

  • Laser-based, non-contact ultrasound NDT
  • High resolution scans 
  • True impulse response, enables single-sided material testing

XARION's Solution for Industrial Process Control

  • XARION’s optical microphone enables real-time surveillance of industrial processes
  • Non-contact measurement – no solid or liquid coupling required
  • Ultrasound sensing up to 1 MHz, allows suppression of background noise
