The night vision goggle devices are one of the electro-optical devices and were developed after 1930’s. It helps to intensify the available ambient light, instead of using the inbuilt light source, to trace out the hidden objects in the deep dark environments.

The night vision goggles use the image intensification technique, to capture and amplify the electrons collected from the ambient light, to show the battlefield through the phosphor screen display. The US scientists make use of this phosphor screen because it is highly sensitive and safe to human eyes than the others.
