How night vision works. http://www.explainthatstuff.com/hownightvisionworks.html 1. Dim light from a night scene enters the lens at the front. The light is made of photons (particles of light) of all colors.

2. As the photons enter the goggles, they strike a light-sensitive surface called a photocathode. It's a bit like a very precise solar panel: it's job is to convert photons into electrons (the tiny, subatomic particles that carry electricity round a circuit).

3. The electrons are amplified by a photomultiplier, a kind of photoelectric cell. Each electron entering the photomultiplier results in many more electrons leaving it.

4. The electrons leaving the photomultiplier hit a phosphor screen, similar to the screen in an old-fashioned television. As the electrons hit the phosphor, they create tiny flashes of light.

5. Since there are many more photons than originally entered the goggles, the screen makes a much brighter version of the original scene. Remember to As seen on COD 4. http://tarorat.blogspot.com/2009_05_01_archive.html I eat prezi's for breaky WAKA WAKA WAKA
