Using a Night Vision Device
It's difficult to see in the dark. Unless there's some light
peeking in through the window or from under a door, our vision
is compromised. If we wait a little while, our night vision
kicks in, allowing us to see somewhat better. It's not enough
that we can read in the dark, but it should be enough to keep us
from stumbling into furniture or tripping over the carpet.
Sometimes though, our human night vision isn't enough and we
need a little help.
That's where technology kicks in. Thanks to science we can use
night vision to do all sorts of things. With the proper
equipment we can hunt, take pictures or even fight wars in the
dark. We can also perform surveillance and search and rescue
missions.
Here's how it works: Your night vision product will take
existing light and amplify it through an objective lens, which
then focuses on an image intensifier. A photocathode located
inside the intensifier converts the photon energy into
electrons. The electrons in turn strike a phosphor screen
creating a viewable image. In reality it looks like
you're
watching television on a green screen.
Atmospheric conditions can affect night vision. For instance, if
it's cloudy, foggy, or overcast, night vision can be
compromised. The clearer the night, the farther one will be able
to see with night vision technology. It should also be noted
that night vision shouldn't be magnified, as light is lost
during the magnification process making it more difficult to see.
Night vision devices include: - Cameras - Binoculars - Scopes
for firearms - Goggles
If you think that using a night vision device on a frequent
basis might be harmful, you couldn't be more wrong. Night vision
products are no more harmful than a television or movie screen.
It doesn't emit radiation or other harmful rays and there's no
reason for it to cause blindness.
