From your smartphone’s face recognition feature to fancy fitness trackers and advanced night vision cameras, many sensors we use daily rely on infrared light detection. For the last eight years, a ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

A new way to make large ultrathin infrared sensors that don’t need cryogenic cooling could radically change night vision for the military or even autonomous vehicles. In a study published today in ...

How transimpedance amplifiers are used in fiber-optic communications, laser rangefinders, and LiDAR systems. How avalanche photodiodes enhance TIA performance. Application-specific design and topology ...

A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors.

The new method, which uses quantum dots, performs as well as or better than current infrared light sources while being much ...

Substantial miniaturization of infrared (IR) sensors is necessary for their incorporation into next-generation portable electronics, wearable devices, and small satellites. However, modern infrared ...
