XARION Laser Acoustics is a provider of unique, laser-based acoustic sensors. The membrane-free optical microphone uses an IP-protected principle of operation: it detects sound based on its ability to change the speed of light. Since no mechanically movable or deformable parts are involved in this approach, the sensor comes with a linear frequency response free from mechanical resonances. The microphone shows an unprecedented frequency bandwidth exceeding state of the art solutions by a factor of ten.

Membrane-free Optical Microphone

XARION's Optical Microphone enables a novel real-time process control approach. As a complementary solution to visual inspection, the sensor monitors processes via air-coupled ultrasound, contact-free.

Features:

  • Membrane-free optical microphone
  • Low self-noise level
  • Frequency range: 10 Hz–2 MHz (acoustics and ultrasound)
  • Dynamic range: 30–180 dB (A) SPL

Typical applications to monitor in the field of laser material processing are:

  • Laser Welding
  • Laser Powder Bed Fusion (LPBF)
  • Laser Material Deposition (LMD – powder or wire based)
  • Extreme high-speed laser material deposition (EHLA)
  • Laser Cladding
  • Laser Texturing or Structuring
  • Laser Micromachining
  • Laser Glass Processing

More information about the technology and the advantages can be found in an article published in the Laser Technik Journal: Download

Further technical articles have been published about the following applications:

  • Laser welding: Download
  • Laser Metal Deposition (LMD) for detection of hot cracks during and after the build process: Download

XARION's Optical Microphone can also be used for any other process in your production. Especially if you run into any limits with thermal, camera-based, optical, mechanical or any other monitoring technology, the acoustic most likely can help. See here a simple but very impressive demonstration:
