Project Description

In the context of increasing demand  for sensitive, selective, fast and portable  detectors for trace components  in gases and liquids, e.g due to increasing concerns  about atmospheric pollutants, and to needs for improved medical screening capabilities for early detection of diseases and drug abuse, the project goal was to build, low cost and robust  platform based on optical spectroscopy  in the near- and mid-infrared range.
