How Night Vision Works :
Night vision devices gather existing ambient light (starlight, moonlight or infra-red
light) through the front lens, in the form of photons. As the photons travel into a
photocathode tube they're scanned for position and intensity. This information is
electrically reproduced in the form of electrons. |
 |
| The electrons are then
amplified through electrical and chemical means. Then, they're hurled against a phosphorus
screen that changes the amplified electrons back into visible light that you see through
the eyepiece. The image will now be a clear green-hued amplified re-creation of the scene
you were observing. **Thanks
to the folks at American Technologies Network for the illustration. |
