Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to ...

A new imaging technology developed at the University of Connecticut promises to rewrite the rules of optical imaging, ...

A multilayered semiconductor acting as an optical sensor opens the way to miniaturized, adjunct spectrometers.

The optical sensor is the first of its kind, Smartkem claims, and can be used for fingerprint or palm biometrics on flexible ...

Analog and digital optoelectronic sensors combine an LED and an optoelectronic integrated circuit in a compact package to enable optical encoders to provide absolute or incremental position detection ...

Fingerprint matrices transform scattered light into clear images, overcoming challenges in opaque environments and paving the ...

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 ...

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 ...

In the pursuit of clean and renewable energy, hydrogen plays an important role. But a major challenge facing this transition is that the gas is explosive when mixed with air. For this reason, it is ...
