How the augmented reality night vision goggles used by the U.S. military work


It is the Enhanced Night Vision Goggle-Binocular (ENVG-B) model, created especially for soldiers. They have a higher resolution stereoscopic display than previous designs and enhance contours to show objects more clearly.

With improved technology, the Lancer Brigade of the United States Army has shown a video that shows what the view is like from night vision goggles with augmented reality. Although these devices are not new, they have improved in recent years, with higher resolution and thermographic images that allow the recognition of targets in environments with poor visibility.

Known as Enhanced Night Vision Binocular Goggles, or ENVG-B, they were designed to enhance a soldier's ability to not only see what is happening around him in any light condition but also to be able to accurately distinguish what he is seeing.

The traditional night vision goggles in their older models worked by converting photons gathered in low-light environments into electrons that were amplified as they passed through a vacuum tube and eventually illuminated a phosphor-coated screen that provided a brighter- than- normal image. They were looking at the glasses.

Thus, the Lancer Brigade has shared the video on Twitter, where it appears performing some maneuvers from the subjective gaze of its new Enhanced Night Vision Goggle-Binocular (ENVG-B) glasses, as an example of the efforts of the US Army to continue modernizing its force. Of combat.

According to the website of the US Army Acquisition Support Center, these glasses were designed specifically for soldiers. They are developed by L3 Warrior Sensor Systems and have the ability to observe and practice in all types of weather conditions with limited visibility and multiple light conditions. In addition, the glasses include augmented reality aspects to orient yourself without removing the glasses.

Kyle Mizokami, who specialized in Defense and Security, has indicated that the video they have shown is an exercise in which they use glasses to "aim, confront and neutralize threats" and that it took place on April 19 at the Lewis Joint Base -McChord, west of Washington state. Glasses have a high-resolution stereoscopic display for quick target identification.

Thus, it separates the objectives from the background and, thanks to a series of phosphor tubes, achieves a greater contrast than that obtained with the system that uses green phosphors present in the rest of the night vision goggles. The double tube binocular system enhances in-depth feedback and situational awareness..

Targets are better-recognized thanks to a fused thermal imager, and the wireless connectivity helps reduce enemy exposure by not requiring the weapon to be held at the shoulder. The device can detect human-sized targets at a distance of 150 meters with a probability of 80 prob and 300 meters with a probability of 50 meters. However, it reaches 300 meters (80%) and 550 meters (50%) in objective values. It has autonomy for more than seven and a half hours of use and weighs less than 1.1 kilos.

This night vision device is complemented by an augmented reality system that enhances the contours to show objects more clearly. The viewfinder has different modes depending on the visibility environments (also depending on the lighting that is available and the weather conditions). Thus, these modes include dust, smoke, underground, or zero illumination.
