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 ...

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.

To shrink size and power consumption for wearables, Rohm has turned to lasers for a short-range proximity detector. Built around a vcsel (vertical cavity surface-emitting laser), RPR-0720 measures ...

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 ...

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 ...

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’ ...

New technology under development at UC Berkeley could soon give bomb-sniffing dogs some serious competition. A team of researchers led by Xiang Zhang, UC Berkeley professor of mechanical engineering, ...
