Click on the image to your right to watch the new "How Night
Vision Works Video produced by ITT Industries. Night Vision technology
consists of two major types: image intensification (light amplification)
and thermal
imaging (infrared). Most consumer night vision products are
light amplifying devices. Light amplification technology takes the
small amount of light, such as moonlight or starlight, that is in
the surrounding area, and converts the light energy (scientists
call it photons), into electrical energy (electrons). These electrons
pass through a thin disk that's about the size of a quarter and
contains over 10 million channels. As the electrons travel through
and strike the walls of the channels, thousands more electrons are
released. These multiplied electrons then bounce off of a phosphor
screen which converts the electrons back into photons and lets you
see an impressive nighttime view even when it's really dark. Click here for more on How Night Vision Works
