Definition: infrared imaging

Detecting infrared radiation. Everything above absolute zero emits infrared radiation, which is also perceived as heat in the far infrared (FIR) range. In normal environments, people and animals emit more infrared than their surroundings, and infrared night vision systems are used to detect objects not easily visible to the naked eye. See infrared.
