There are two basic types of night vision binoculars: image enhancement and thermal imaging. Picture enhancement binoculars are the first type most people think of – with the green screen that can produce a detailed picture of almost total darkness. These night vision binoculars detect small amounts of visible light and amplify it until it is strong enough to be seen. Thermal camera binoculars, however, don’t pick up the visible light at all. Instead, collect the infrared radiation released by agencies and other hot objects.

Image Enhancement

Image enhancement night vision binoculars first capture lighting in a normal lens. That light is shone into a device called the picture tube. After that, another device called the photo cathode is used to convert photons the individual electrons and then is accelerated down a tube. The electrons then hit a phosphorus screen the same way as the display cathode-ray TV. Displayed energy is absorbed by the electrons of the individual publications, and the green light. This green light is then shone through the lens of the eyes of another viewer.

Thermal Imaging

Thermal imaging systems detect infrared night-vision light. Infrared heat is released by all warm objects. Heat is energy. Heat causes some of the object’s electrons to become excited and jump to a higher state. These electrons lose energy that comes back to the lower state and transmits an infrared photon. People can’t normally see these IR photons, infrared thermal imaging binoculars can. Infrared light from the object shines through the lens of a digital camera, which consists of a network of tiny light detectors. A small computer image produced by light is then displayed through the eyepiece. Not only that shows the viewer the form of objects, but also shows how hot it is all because hotter objects emit more light and infrared light in different colors. As people and animals are warmer than trees and other basic things, this type of camera allows the viewer to see, even when it is completely dark.
