The Benefits of Trunking SIP

History of Night Vision Goggles (nvg)

Darkness has always been an issue during the war, how do you fight an enemy you cannot see. Prior to the discovery of night vision technology, soldiers battled during the night with various primitive methods, including the use of fire, and more modern times, electric search lights.

But on the battlefield these methods were also a disadvantage , not only could they see the enemy but the enemy could see them, and what they were up to. Modern night vision googles make up for this by huge factors.

During the mid 60ò€™s the clever people who first worked on night vision technology created what has become known as the first generation night vision device. This was a passive unit, and the first was know as a Starlight Scope, which could be used as a rifle scope. This was the first major practical use in the military of night vision units.

Over the years engineers and scientists continued on this technology to deliver the second, third, and now fourth generation night vision equipment, and they continue to come up with new ideas as research efforts pay off.
