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

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 ...

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 ...

From autonomous vehicles to optical testing, these sensors bring high performance infrared detection into real-world systems.

Samsung Semiconductor opened CES 2026 with a major imaging milestone, unveiling the ISOCELL HP5, the smallest 200-megapixel ...

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 ...

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 ...
