Green Night Vision
ADDPMP723
Night vision is the ability to see in low-light conditions, either naturally with scotopic vision or through a night-vision device. It requires both sufficient spectral and intensity range. Humans have poor night vision compared to many animals such as cats, in part because the human eye lacks a tapetum lucidum, the tissue behind the retina that reflects light back through the retina thus increasing the light available to the photoreceptors.
The night vision goggle is a night vision device with dual eyepieces. The device can utilise either one intensifier tube with the same image sent to both eyes, or a separate image intensifier tube for each eye. Night vision goggles combined with magnification lenses constitute night vision binoculars. Other types include monocular night vision devices with only one eyepiece, which may be mounted to firearms as night sights. Night vision systems can also be installed in vehicles. Automotive night vision systems are used to improve driver perception and their ability to see further in darkness or poor weather. Such systems typically use infrared cameras, sometimes combined with active illumination techniques, to collect information that is then displayed to the driver. They are currently offered as optional equipment on certain premium vehicles.
Night vision goggles are intentionally designed to produce green images because the human eye is more sensitive to wavelengths of light around 555 nm, which are dominated by the colour green. Moreover, it’s easier and more comfortable for people to watch a green screen for longer than they could a black and white one. So, by turning the images green, the natural night vision of a human is enhanced when wearing goggles.
