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 ...

Researchers have developed a tiny, electrically tunable infrared filter that could help shrink bulky thermal sensing systems ...

The Catfish 757 has spent decades supporting the F-22 program, and that work now extends to testing external stores.

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 ...

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, ...

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 ...

Smart, low-cost and portable gas sensors are highly desired due to the importance of air quality monitoring for environmental and defense-related applications. Traditionally, electrochemical and ...

Optical sensors with in-cell logic and memory capabilities offer new horizons in realizing machine vision beyond von Neumann architectures and have been attempted with two-dimensional materials, ...

Researchers developed a type of infrared photodiode that is 35% more responsive at 1.55 m, the key wavelength for telecommunications, compared to other germanium-based components. Detecting infrared ...

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 groundbreaking infrared sensors use layers of repeating molecular structures to interact with individual photons, or units of light. The sensors resolve more wavelengths of infrared at a higher ...

While a mosquito bite is often no more than a temporary bother, in many parts of the world it can be scary. One mosquito species, Aedes aegypti, spreads the viruses that cause over 100,000,000 cases ...
