As far as night vision goggles are concerned, from low light level to infrared then to the current thermal imaging, at least three revolutions have been experienced. Is infrared thermal imaging useful?
Thermal imaging presents a temperature distribution map by sensing the surface temperature of an object, which is different from our usual visible light cameras. And it is said that it can be completely night vision, that is to say, even if it is completely dark, it can be viewed without light, and it can also penetrate smog and dense smoke. But as far as we know, the price of thermal imaging products is not low, how can it be integrated into people's

It was first applied to the military, and later in industries that require temperature measurement such as electric power industry, in some competitions, infrared can ensure safety. If someone gets lost, it can help find the hot spot humidity of the person.
The low-light night vision device cannot be used during the day, and it has certain conditions to use it at night, that is, it must use a certain light source, such as moonlight, and the effect of using it in complete darkness is not so good.
The digital night vision device is basically dual-purpose for day and night. It has good infrared ability in night mode. As long as the illuminator is designed well, it can reach an effective observation distance of more than 200 meters in total darkness.

Infrared night vision thermal imaging is the addition of thermal imaging on the basis of night vision. It is very sensitive to the capture of heat sources. Thermal imaging is generally used to capture remote personnel and mobile equipment, because it is not easy to observe the target from a long distance. With the characteristics of thermal imaging, the heat source can be used to determine whether the target is a living body or vehicle with a heat source.

Simple low-light-level night vision devices cannot perform thermal imaging, while infrared night vision devices actually rely on thermal imaging to identify targets at night.
