1. There are two general kinds of night vision. Thermal imaging uses
infrared technology, and light amplification uses existing ambient
light.
2. Thermal imaging gathers all surrounding infrared light and
creates a picture according to the light's temperature patterns. This
"thermogram" is then converted and processed into a clear, recognizable
image.
3. Light amplification takes all ambient light, such as starlight,
moonlight, and infrared light, and converts it into electrical energy
and then back into light, allowing you to see in near-total darkness.
4. Night-vision binoculars
do possess some magnification qualities, but you shouldn't depend on
them for extreme distance-viewing or clarity. Their real function is to
allow you to see a fair distance in low-lit conditions.
5. Night vision rifle scopes allow for precision and stealth, even in
the lowest light conditions. Some models can even shift from day to
night vision in seconds.
6. Some advantages to night-vision goggles are their small size and typically included head mounts. These allow for maneuverability and portability.
7. Night-vision phosphor screens are colored green because the human
eye can differentiate between different shades of green better than any
other phosphor color.
