What are the main differences between night vision devices and thermal imaging night vision devices?
1. In the case of total darkness, the advantage of thermal imaging night vision devices is obvious
Due to the fact that thermal imaging night vision devices are not affected by light, the observation distance of thermal imaging night vision devices under all black and normal light is exactly the same. However, second-generation and above night vision devices must rely on auxiliary infrared light sources in completely black conditions, and the distance of the auxiliary infrared light source is generally only up to 100 meters. So in very dark environments, the observation distance of thermal imaging night vision devices is much farther than that of traditional night vision devices.
2. In harsh environments, thermal imaging night vision devices have significant advantages
In harsh environments such as foggy and rainy days, the observation distance of traditional night vision instruments will be greatly reduced. However, the impact on thermal imaging night vision devices will be minimal.
3. In environments with significant changes in light intensity, the advantages of thermal imaging night vision devices are obvious
We all know that traditional night vision devices are afraid of strong light, although many traditional night vision devices have strong light protection. However, if the ambient brightness changes significantly, it will have a significant impact on the observation. But thermal imaging night vision devices are not affected by light. It is precisely for this reason that top-level car mounted night vision systems, such as those on Mercedes Benz and BMW, use thermal imaging systems.
4. In terms of target recognition ability, traditional night vision devices have advantages over thermal imaging night vision devices.
The main purpose of thermal imaging night vision equipment is to discover targets and identify target categories, such as whether the targets are humans or animals. Traditional night vision devices, if they have sufficient clarity, can identify the target of a character and clearly see their facial features.
