The instinctive reaction when measuring nuclear radiation is to think of a Geiger counter, as the low-pressure gas tube detectors have entered our popular culture through the Cold War. A G-M tube ...

Avalanche photodiodes (APDs) and photodetectors are ... relevant for applications requiring precise detection of weak light signals, such as in autonomous driving and quantum communication.

For the last eight years, a team of researchers at Aalto University in Finland has been working to improve the efficiency of photodiodes, a type of infrared sensor that converts light into ...

The work is described in an article published on 1st Jan 2025 in the journal Light: Science & Applications. “It took us eight years from the idea to proof-of-concept,” said Prof. Hele Savin. “The ...

The IR light hits your finger and bounces back to the photodiodes on the bar ... When I put this one sensor stick back together, an area near the custom ASIC gets hot. Sacrificed for my idle ...

Around 80% of the pixels on the image sensor incorporate two separate light-sensitive photodiodes. The signal from these is combined when capturing an image, but can be split during autofocussing ...

Manufacturer of standard and custom silicon, SiC, LAAPD, InGaAs and extended InGaAs photodiodes and detectors and CdS ambient light photocells for industrial, medical, homeland security and military ...
