Radar detectors are designed to pinpoint the presence of radar and laser sensors that police and law enforcement use to calculate your driving speed—hopefully in time to help you avoid getting a ...

Physicists develop innovative technique using carbon-dioxide lasers to detect radioactive materials from safe distances for national defence and emergency response.

From many viable technologies, four REDSCAN RLS-3060 detectors were chosen as the preferred security solution. The award-winning REDSCAN RLS-3060 laser detectors from Optex were installed to create ...

Nevertheless, the American physicists Kip Thorne and Rainer Weiss, later joined by the Scottish physicist Ronald Drever, dreamed of building a laser-based gravitational wave detector, and they set ...

Researchers say findings provide compelling evidence underscoring the potential of electric-field molecular fingerprinting for minimally invasive disease detection.

Crucially, the researchers were able to amplify this backscatter as it travelled back through the laser system, substantially improving detection sensitivity. A compelling advantage of using long ...
