Figure 1a shows a slotted optical switch. An LED is mounted in a plastic housing, facing a phototransistor, but separated by a gap. If something moves into the gap, it blocks the light path between ...

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 ...

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 ...

The very low maintenance of optical sensors has transformed dissolved oxygen measurement at one of Brazil’s biggest power plants. Critical measurement for corrosion prevention. In the lush forests of ...

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

When the 2025 Nobel Prize in Chemistry honored Omar Yaghi—the "father of metal-organic frameworks," or MOFs—along with Susumu Kitagawa and Richard Robson, it celebrated more than the creation of a new ...

AINEX to Launch Nextick Mouse Featuring Optical Sensor Technology Proven in Nextick Lightgun Pro in February 2026 Our ...

Sensors help microprocessor-based systems find their bearings. Where would embedded systems be without them? Sensors provide the windows through which microprocessor-based systems can observe their ...

There is a point where taking technology for granted hides some of the incredible capabilities of seemingly simple devices. Optical mice are a great example of this principle, using what are more or ...
