Research & Development

To explore and leverage novel sensing approaches enabled by the membrane-free optical microphone technology, XARION pursues a number of national and international research collaborations.

The optical microphone technology is protected by several patents, including patents granted in the United States, the European Union, China, South Korea, Japan, and other countries. The company’s scientific advisory board is headed by T.W. Hänsch, Nobel laureate and laser physicist.

Photoacoustic Imaging (PAI)
The interaction of a short laser pulse with biological tissue generates ultrasound. This is the basic principle behind Photoacoustic Imaging, a rapidly emerging biomedical imaging technique. XARIONs liquid-coupled version of the optical microphone has shown to be a perfect match for Photoacoustic Imaging: some of its advantages are its excellent sensitivity at compact sensor size, optical transparency for the through-excitation by lasers used in PAI, and stray-light immunity. Current research focuses on Photoacoustic Laparoscopy, as well as fast-scanning optical-resolution Photoacoustic Microscopy (OR-PAM).
