Researchers have created a plasmon laser detector that can sniff out tiny traces of airborne molecules of explosives. The sensor detected both DNT and ammonium nitrate at concentrations below one part ...

Leading sensor manufacturer OPTEX has announced the roll out of its outdoor and high-resolution indoor laser sensor RLS-2020S, complementing its next-generation REDSCAN mini sensor that features a ...

Ultra-sensitive infrared detectors originally built for defense and telecoms are moving into premium hunting and long-range ...

Research scientist and entrepreneur Sverre Dokken believes laser-based remote sensing has big potential in the maritime domain. But what is LADAR, who’s it for and what are the key benefits? “Our ...

From autonomous vehicles to optical testing, these sensors bring high performance infrared detection into real-world systems.

Japanese researchers are pushing quantum technology to the point where it can register unimaginably small disturbances, ...

The UK government has awarded a £180K grant to Sentinel Photonics to develop a sensor to detect and identify laser threats in civilian contexts. The original technology was created by the Dstl ...

Remember the days of the simple photo-electric cell? Using either a transmitter-receiver pair or a single TX/RX with a retro-reflector, the interruption of an IR beam would trigger an alarm, stop a ...

Mid-infrared spectroscopy is one of the main techniques for chemical sensing. Molecules can be identified through their unique pattern of absorption lines, which give rise to the ‘fingerprint region’ ...
