Night vision goggles are one way to make you see images clearly when you are in total darkness. These goggles are usually used by law enforcement officers and military officers. But night vision goggles are also available to the public now.
Military night vision goggles are made of an image intensifier tube, water proof time and a mounting mechanism. The infrared band detects ambient light which reflects on the area being viewed. A powerful electric field then pulls the electrons towards the screen which makes the phosphor screen produce the bright images.
Night vision goggles were first used during World War II and were used mostly in the Vietnam War. Seeing how effective they are, the field of law enforcement also found their way in using them for their profession for rescue and surveillance purposes.
The use of military night vision goggles are regulated by law when it comes to certain countries. Be sure to read on the laws when it comes to the uses of these night vision devices. There are some types and classes of night vision goggles that are only allowed for military use. Civilians are only allowed to use a lower class of these night vision goggles.
