This infrared detector circuit uses a passive IR-detector component PID20. It converts heat radiation into electrical impulses. The output voltage of the PID20 increases when an object comes close to ...

An obstacle detection unit is an essential part of a variety of projects, such as robotics and security applications An obstacle detection unit is an essential part of a variety of projects, such as ...

(InfraRed detector) A sensing device that picks up radiation in the infrared band. Used extensively for still and video night vision cameras, cooled IR detectors can sense the makeup of nebulae light ...

Jülich researchers, together with Italian and German colleagues, have developed a particularly cost-effective infrared detector that can be easily integrated into existing camera chips and smartphones ...

InGaAs detectors have paved the way for near-infrared detection in industrial applications. Bob Grietens of XenICs describes the latest advances in InGaAs NIR camera technology. Commercially available ...

Polarization, as a primary physical quantity of light, is of great interest to almost all optical sciences and technologies. Along with linear polarization detection, circular polarization (or light ...

For decades infrared detector development has drawn on many different types of material. Philippe Tribolet explains why Sofradir has selected HgCdTe for its future plans. These include building a new ...

With sensor technology becoming increasingly fundamental to a world driven by big data, photonics is also riding on the wave. VIGO Photonics, a Polish company founded in 1987 and specialized in ...

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 ...
