A new metasurface chip from MIT electronically tunes infrared light without mechanical components, opening new possibilities ...

MIT’s infrared chip bends heat light pixel by pixel, powering smarter thermal cameras, gas detection, and next‑gen optical ...

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 ...

FPAs are image sensors that convert infrared light into electrical signals to produce real-time thermal images and are widely ...

We all know that feeling: you've turned the lights off and are almost asleep when you hear that infamous buzz. A mosquito is hunting in your bedroom. The dance commences. You could turn on the lights, ...

Invisible to our eyes, shortwave infrared (SWIR) light can enable unprecedented reliability, function and performance in high-volume, computer vision first applications in service robotics, automotive ...

Scientists have developed a lens-free mid-infrared camera using a modern twist on pinhole imaging. The system uses nonlinear crystals to convert infrared light into visible, allowing standard sensors ...

A newly granted Chinese utility model patent proposes a self-cleaning, retractable filament sensor for FFF 3D printers.

Electro-optical detectors are used to measure or sense the radiation emitted or reflected by objects within the detector’s optical field of view (FOV). Passive systems operate without any illumination ...
