CU Boulder researchers have built high-performing optical microresonators, opening the door for new sensor technologies. At its simplest form, a microresonator is a tiny device that can trap light and ...

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 ...

Successful flight trials done for the Australian Defence Force (ADF) across multi-domains prove the utility of AI-enabled, persistent, wide-area motion imagery for long-range surveillance at a greater ...

Using their Mosquito fabrication method, the researchers created a fan-out pattern of multiple thin light paths inside a thin sheet of PDMS. This created four optical channels that could be used for ...

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 ...

From Disney World to the smartphone in your pocket, fingerprint scanners have become commonplace these days. Even budget phones sport the tech, sometimes alongside other biometric unlocking options ...

Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The approach uses multiple sensors to collect raw light patterns independently, then ...

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 ...
