(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 ...

One of the coolest things about infrared cameras is that you can point them at a scene and get a visual image of how hot or cold things are. So … what if those things are humans? Could you use an IR ...

Entry-level IR cameras with microbolometer detectors operate according to nonquantum principles. The detectors respond to radiant energy in a way that causes a change of state in the bulk material, ...

IR sensors rely on an emitter (IR LED) and a detector (photodiode or photoresistor) to measure infrared light and convert it ...
