When you think of night vision goggles, you might imagine that the dark night is illuminated by the green ocean, which helps to improve visibility. Now, this is an ancient technology, because the Lancer Brigade at Joint Base Lewis-McChord of the US Army shows what soldiers see through the army’s newest and best night vision goggles. The predator will be jealous.
The new type of goggles called Enhanced Night Vision Binoculars (ENVG-B) is designed to greatly improve soldiers’ ability to not only see what is happening around them under any lighting conditions, but also accurately Identify what they see. This is the biggest problem with traditional night vision goggles. The old working principle was to convert photons collected in a low-light environment into electrons. These electrons are amplified as they pass through a vacuum tube and eventually light up the phosphor-coated screen, providing a brighter image seen by the goggles.
The traditional green of night vision technology was chosen because it is considered the easiest color to watch for a long time in the dark. But bright images lack contrast and are usually very noisy, which makes it difficult for users to understand what they are actually seeing. This is especially problematic for soldiers in combat.
The new ENVG-B night vision goggles upgrades the green fluorescent tube to a white fluorescent tube, resulting in better contrast and brighter images. The existing technology is combined with enhanced functions, including a thermal imager that can penetrate obstacles such as dust and smoke, and it can work normally even when the external lighting is zero, such as underground, and it also adds real-time edge detection and other enhancements. Reality enhancement function to enhance and outline objects like companions. The goggles can even communicate wirelessly with the electronic sight on the weapon, allowing soldiers to view it remotely and aim at the target without exposing themselves to threats.

The Army’s new ENVG-B goggles solve another problem of traditional night vision technology, which is the lack of stereo vision. The human brain is much better at evaluating what it sees and tracking targets with full depth perception, but the high cost of electronic equipment required to achieve night vision means that it is much cheaper to equip soldiers with monoculars with this technology . ENVG-B goggles use a "dual-tube binocular system", which allows soldiers to watch in 3D at night, and also provides the flexibility to flip any tube, so the night vision function can be used to enhance the soldier’s natural vision I saw it through my own eyes.
The weight of ENVG-B goggles is about 2 pounds, not as light as binoculars, because they still rely on batteries to keep running for about 8 hours after charging, but they are smaller and lighter than the old models. The technology does not require uncomfortable heads. Bring to fix them. They just flipped over from the bracket in front of the soldier's helmet. This technology seems to be a game changer, and hope that it will work as promised in the field so that it can penetrate into consumer products within a few years.
