In the realm of non-contact distance and thickness measurement, confocal chromatic sensing is highly regarded for its ...

Researchers have developed a new optical sensor that provides a simple way to achieve real-time detection of extremely low levels of arsenic in water. Researchers have developed a new optical sensor ...

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 ...

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 ...

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 ...
