This small Austrian spin-out company comes out with something that might be revolutionary for the audio recording process too.
XARION Laser Acoustics GmbH was founded in 2012 as a spin-out company by the Vienna University of Technology and the Knowles Corporation. The invention of the Optical Microphone dates back to 2006. Its technology was subsequently developed together with Philips/NXP Sound Solutions and ultimately led to the founding of XARION. At XARION, we are excited by the prospect of providing novel and path-breaking sensing capabilities. It is our mission to make this technology a key factor in such diverse application fields as acoustic metrology, non-destructive material testing, medical imaging, and consumer electronics.
XARION enjoys the dedicated support of a distinguished circle of stakeholders, including XARION’s largest shareholder Hans-Peter Porsche, Member of the Supervisory Board at Dr. Ing. h.c. F. Porsche AG and Porsche Holding Salzburg; and Theodor W. Hänsch, Nobel laureate in physics, as head of the XARION Scientific Advisory Board.
XARION’s patent-protected sensor technology platform is to offer substantial advantages:

XARION’s patent-protected sensor technology platform is to offer substantial advantages:
- Transducer with a perfectly linear frequency response. Although the enclosure needs to be carefully designed to minimize its influence on the sound field, the transducer itself is not frequency dependent.
- Sound detection in air and liquids
- Extreme ultrasound frequency range from 10 Hz up to 1 MHz in air, 25 MHz in liquids
- Qualification for ultra-high SPL (up to 190 dB)
- Outstanding mechanical stability and acoustical shock resistance
- Since no moving inert mass is involved, the Optical Microphone has a true temporal impulse response.
- For the fiber-coupled embodiment, operation in hazardous environments such as in high electromagnetic fields or explosion endangered areas is feasible.
- In array applications, the inherent phase match between the single cells can be a crucial advantage. Hence, targeting spatial resolution closer to the theoretical limit is possible.
- Due to its non-invasive principle of operation, the microphone is to exhibit a reduced susceptibility to wind noise and structure-borne sound.
- State-of-the art signal-to-noise ratio and dynamic range, zero intermodulation distortion combined with a small device size.
- Cost efficiency due to wafer level optics technology (consumer electronics applications)
