Researchers from Skoltech have devised a way to detect infrared radiation across a wide range without cooling the detector.

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 ...

The Fraunhofer Institute for Photonic Microsystems (IPMS), in collaboration with Heimann Sensor and the Leibniz Institute for Solid State and Materials Research Dresden (IFW Dresden), is developing ...

The frequency regime lying in the shortwave infrared (SWIR) has very unique properties that make it ideal for several applications, such as being less affected by atmospheric scattering as well as ...

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 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 ...

Researchers have developed an innovative photodetector capable of detecting a broad range of mid-infrared spectra. NASA's James Webb Space Telescope (JWST) utilizes mid-infrared spectroscopy to ...

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 ...
