Recently, a new type of night vision device has officially entered service in the US military, attracting attention from the outside world. The manufacturer has clearly stated that this product is only for use by the US government and law enforcement agencies, and is not sold to civilian users. This has further sparked people's curiosity about what kind of product it is.

The AN/PSQ-20B enhanced night vision device, also known as ENVG, is a helmet mounted and handheld device that combines the low light level capability of night vision image enhancement devices and the thermal sensitivity of thermal imaging systems. It can observe, detect, and recognize targets under harsh conditions including light rain, light smoke, light snow, low light to complete darkness.

As an integrated system, ENVG allows for adjusting images from 100% low light night vision mode to 100% thermal imaging mode, or displaying both simultaneously, that is, displaying the infrared signal features of the target on low light images. It amplifies the available light and thermal signals and fuses them together to produce clear images. This cutting-edge technology provides significant advantages for warfighters on the battlefield, as it has both advantages and can increase the probability of mission success and battlefield survivability.

ENVG provides better situational awareness capabilities due to improved fusion technology for threat detection. It allows operators to see more battlefield blur than any other device. On its own, the standard L-3 Gen3 infinitely automatic gated I-type electronic tube produces high-quality images and superb resolution, providing excellent recognition capabilities. However, even the most advanced micro light tubes still rely on available environmental lighting conditions. The more abundant the light, the better the imaging (more details, higher distance resolution). However, battlefield conditions do not always allow for optimal ambient light. On cloudy nights with little moonlight, thick leaves, or in rooms with no light, the low light tubes will completely fail. In addition, meteorological factors such as heavy rain, fog, snow, and smoke can also limit imaging quality. This is when the thermal imager comes into play. Thermal imaging recognizes infrared light without relying on visible light. Thermal imaging can penetrate most obscurations and can image in completely dark environments. Unfortunately, the thermal imager cannot produce image details at the same level as the low light level tube, which limits its recognition ability.

Therefore, ENVG integrates these two technologies, providing users with a thermal imaging coverage layer that does not affect the normal operation of the low light level tube. This provides soldiers on the battlefield with great situational awareness capabilities, with threats everywhere. The faster they perceive and recognize the enemy's position, the more they take the initiative. Enemies who are usually hidden by cover such as leaves and rocks can now be easily detected within a safe distance and are particularly effective in urban operations. It's no exaggeration to say that American soldiers wearing AN/PSQ-20B night vision devices are like turning on perspective plugins in a game.
