A new lens-free imaging system uses software to see finer details from farther away than optical systems ever could before.

Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The ...

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 ...

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 ...

Patients who remain in bed for long periods of time may develop pressure sores, which can in turn become potentially life-threatening chronic skin ulcers. A new sensor could help keep that from ...

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 ...

Air bubble sensors are used to detect air or gas bubbles in flexible clear plastic tubes. They are intended to prevent air infusions. The air bubble sensor has no contact with the liquid and is ...
