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 ...

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 ...

Detecting infrared light is critical in an enormous range of technologies, from remote controls to autofocus systems to self-driving cars and virtual reality headsets. That means there would be major ...

Revisiting well-known semiconductors, engineers have produced a low-cost approach to infrared emitters and sensors with potential environmental, medical, and industrial applications.

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.

A new software tool enables quicker integration of infrared sensors by optimizing product design’s evaluation, development, testing, and validation phases. More specifically, the tool streamlines ...

Anduril's new Iris AI-enabled EO/IR sensor riding atop the skin of an unidentified tactical fighter platform. The fighter was likely manned but the company says Iris is primarily intended for unmanned ...

SAN FRANCISCO – Washington-based startup Hydrosat is preparing to send its first thermal-infrared instrument into orbit July 8 on SpaceX’s Transporter-11 rideshare flight. The instrument, designed to ...

As radar technology continues to advance, it offers an increasingly broad range of capabilities, making it a viable alternative to traditional passive infrared (PIR) sensors. With radar’s enhanced ...

For Part 1, click here. High-speed optical communications applications have some high-level transimpedance-amplifier (TIA) circuit similarities with laser rangefinders (LRFs) and LiDAR. However, there ...
