Satellite-based electro-optical sensors are intended to detect missile launches early on, gaining valuable time for initiating countermeasures in case of an attack. The Fraunhofer Institute of ...

A dust sensor is an optical electronic system to detect fine particles such as dust. In principle, an optical dust sensor detects the dust particle concentration the in air by using an optical sensing ...

Scientists at Oxford University have developed a novel sensor made of incredibly thin strands of sapphire that can withstand extreme heat and radiation. The breakthrough is billed as a solution to a ...

Cameras may soon see without lenses, and the change could be as profound as the leap from film to digital. A new imaging technology developed at the University of Connecticut promises to rewrite the ...

We’ve all heard of the smoke test, and we know that it’s the lowest possible bar for performance of an electronic device. If it doesn’t burst into flames when power is applied, you’re good to go for ...

Apple has filed for a patent (number 20210157414) for an “optical sensing device” that involves an Apple Watch that can recognize gestures. In the patent filing, the tech giant optical sensors for ...

A prototype optical sensor thought to be capable of providing an early warning if a bridge is at risk of scour - the number one cause of bridge collapse globally - has been developed by a Queen's ...

Apple is working on new fingerprint sensing technology that could work through an iPhone display by taking advantage of off-axis angular light. In a new patent application, Apple hones in on optical ...
