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 ...

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 ...

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

Maxim Integrated introduces it’s new MAXREFDES27# IO-Link subsystem reference design that lets operators tune and calibrate an optical proximity sensor with excellent accuracy, up to 14 bit resolution ...

Machines are moving beyond single-point sensing. Multi-sensor fusion now delivers vision, ranging and inertial data. The ...

For decades, people with diabetes have relied on finger pricks to withdraw blood or adhesive microneedles to measure and manage their glucose levels. In addition to being painful, these methods can ...

For electrical engineers working in almost any part of the wired or wireless spectrum, the spectrum analyzer is a critical test and measurement tool. For optical engineering, the equivalent tool is ...

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 ...

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 ...

Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to unlocking microscopic details inside living cells. Yet despite decades of ...
