A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors.

A research team at China’s Xidian University says it is developing a silicon-germanium (SiGe) approach for short-wave ...

The first room-temperature light detector that can sense the full infrared spectrum has the potential to put heat vision technology into a contact lens. Unlike comparable mid- and far-infrared ...

The Defense Advanced Research Projects Agency (DARPA) has announced a new program which seeks to enable quantum-level infrared (IR) detection at room temperature. The IR spectrum is a vast information ...

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 ...

The devices, which operate on a heterojunction-gated (HG) structure, demonstrate high responsivity and detectivity while maintaining a simplified fabrication process. This approach avoids the ...

Sofradir, a manufacturer of advanced infrared detectors for military, space and industrial applications, is claimed to have taken the leadership of the global market for supplying second-generation ...

Advanced-technology sensors, coupled with data processing and fusion and networked communications, have enabled new approaches to warfighting and have been essential for reducing combat losses, ...
