An infrared detector is a detector that reacts to infrared (IR) radiation. The two main types of detectors are thermal and photonic (photodetectors). The thermal effects of the incident IR radiation can be followed through many temperature dependent phenomena. [2] Bolometers and microbolometers are based on changes in resistance.
Night vision devices may be passive, relying solely on ambient light, or may be active, using an IR (infrared) illuminator. Night vision devices may be handheld or attach to helmets . When used with firearms, an IR laser sight is often mounted to the weapon.
