How night vision works:
Most of the night vision goggles consist of image intensifier tubes, a waterproof body and mounting mechanism. Work in the near infrared bands to detect environmental light of the reflection is seen. image intensifier tubes for night vision goggles then extended to a weak light, using the photoelectric effect. Tube, the photons of light in to a flap that opens up the number of electrons.
The military uses two main types of night vision goggles:
• Image Intensifiers
Image intensifiers work by expanding the ambient light (flashlight enemy, moonlight, starlight) so you can see, as you would in the day.
• Infrared Lenses
Infrared lenses to convert the infrared spectrum of visible light, but retail prices, which is low.
