Ultra-broadband infrared gas sensor for pollution detection

Air pollution is one of the largest risk factors for disease or premature death globally, yet current portable monitoring technology cannot provide adequate protection at a local community level.

  • TRIAGE will develop a smart, compact and cost-effective air quality sampling sensor network for the hyperspectral detection of all relevant atmospheric pollution gases
  • Resolution and selectivity will be significantly better than current solutions and lower cost
  • Cloud-based deep-learning algorithms will enable automated short-term alerts and long-term trend analysis
  • Extensive testing in urban settings with Swedish and Swiss environmental agencies and transport companies.

In TRIAGE, several technologies will be developed, integrated and demonstrated:

  • 2-10 µm supercontinuum sources by NORBLIS and DTU
  • Rugged low noise 2 µm pump laser by NKT Photonics
  • High-performance multi-pass absorption cell by Senseair
  • Infrared detector modules by VIGO System
  • FT spectrometer by Radboud University
  • The system will be integrated by CSEM
  • Reference database by Radboud University
  • Analysis and deep learning algorithms by CSEM


Linköping University will be responsible for the tests of functionality and long-term demonstration of the TRIAGE system.
