How Does Night Vision Work?

Night Vision is not just for spy work or high tech movies. Night Vision is a powerful tool with the ability to hunt, patrol, and maneuver at night with little ambient light. Ambient light can be the moon, stars or other man-made sources, such as streetlights. Light enters the night vision system through the objective lens and convers the light (photons) into a high-energy charge (electrons) from the power supply. These electrons pass through a photoelectric plate (thin disc) that contains over 10 million cannels. This produces thousands more electrons by using a very high voltage to propel them down a tube. The electrons travel through a phosphor screen (like a TV screen) and convert back to photons (light), which is visible to the human eye. The image is viewed through the eyepiece. All night vision images are green because the human eye can differentiate more shades of green than any other color.
