Real-time chemical sensor to improve airport security
A team of European scientists has created a hand-held chemical sensor capable of instantaneous detection from a distance of 30m. Harnessing new photonics technology, the mid-IR sensor uses spectroscopic sensors that read the unique frequencies, or ‘signatures’, given off when liquids or gases interact with light.
Capable of a detection rate of one every few seconds, the device is six times faster than state of the art trace portal scanners.
The MIRPHAB, or ‘Mid-Infrared photonics devices fabrication for chemical sensing and spectroscopic applications’ project, is being coordinated by CEA-Leti, France, and has received funding of €13million from the European Commission's Photonics Public Private Partnership under the Horizon 2020 program, and €2m from the Swiss Government.
