Inspired by the infrared sensory organs of snakes, which allow them to detect prey in complete darkness, researchers at UNIST ...

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 ...

Shortwave infrared light (SWIR) sensors are desirable in a broad range of applications, particularly in the service robotics, automotive, and consumer electronics sectors. Colloidal quantum dots tuned ...

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 ...

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.

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 ...
