Infrared sensing snakes use pit organs extensively to detect and target warm-blooded prey such as rodents and birds. Blind or blindfolded rattlesnakes can strike prey accurately in the complete absence of visible light, [13] [14] though it does not appear that they assess prey animals based on their body temperature. [15]
Thermal weapon sights are often used by hunters to aid in the detection of game, such as feral hogs, coyotes, or rodents such as rats. The sight's ability to see unaided even in complete darkness allows the hunter to be undetected and aware of potential prey, facilitating a quick and precise takedown. [3]
Infrared is used in night vision equipment when there is insufficient visible light to see. [34] Night vision devices operate through a process involving the conversion of ambient light photons into electrons that are then amplified by a chemical and electrical process and then converted back into visible light.

Infrared vision or thermal vision may refer to: Thermography, the measurement of infrared radiation by thermal camera or similar instrument; Night vision, the improved ability to see in low-light conditions using night-vision devices; Thermoception, the detection of infrared radiation by an organism
Vampire bats have developed a specialized system using infrared-sensitive receptors on their nose-leaf to prey on homeothermic (warm-blooded) vertebrates. [1] Trigeminal nerve fibers that innervate these IR-sensitive receptors may be involved in detection of infrared thermal radiation emitted by their prey. This may aid bats in locating blood ...
Active infrared night-vision combines infrared illumination of spectral range 700–1,000 nm (just over the visible spectrum of the human eye) with CCD cameras sensitive to this light. The resulting scene, which is apparently dark to a human observer, appears as a monochrome image on a normal display device. [ 15 ]
Red light therapy is a type of phototherapy that uses low levels of red light to trigger blood flow and energize cells, which can have healing properties, explains Billy Huh, M.D., Ph.D., a ...
Researchers have observed that among all forms of radiant heat, only far-infrared radiation transfers energy solely in the form of heat that can be sensed by the human body. [12] They have found that this type of radiant heat can penetrate the skin up to a depth of approximately 1.5 inches (3.8 cm).
