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 ...

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

Two recent announcements from developers of infrared sensors point the way towards new applications for thermal imaging systems, as the technology behind them continues to make rapid strides. At the ...

Hamamatsu Photonics has announced the release of the G17242/G17243-0808T indium gallium arsenide (InGaAs) area image sensors.

As evidenced by the Covid-19 pandemic, quick and non-invasive techniques to assess body temperature have become necessary. In various locations, including hospitals, airports and schools, non-contact ...

The visible light spectrum that humans perceive spans only a small portion of the electromagnetic spectrum — roughly 430 to 750 THz, corresponding to wavelengths of ~400-700 nm. Just beyond this range ...

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 ...

Olympus has partnered with the Tokyo Institute of Technology to develop a new imaging sensor that is capable of capturing both color information and near-infrared information simultaneously. This is ...

NASA's James Webb Space Telescope (JWST) utilizes mid-infrared spectroscopy to precisely analyze molecular components such as water vapor and sulfur dioxide in exoplanet atmospheres. The key to this ...
