The differences between infrared thermal imagers and night vision devices
1. Effectiveness and Effect
1) If you have used a regular night vision device, you will find that the observation experience is completely different from that of a regular infrared thermal imaging device. This is because typical night vision devices observe targets directly through the lens, so the field of view they see is the same as that of a telescope lens, circular, and the image is green. If the clarity is sufficient, it is possible to identify who the target person is and see their facial features clearly.
2) The infrared night vision thermal imaging device sees the image on the internal LCD screen, rather than directly seeing the target, so the field of view is square. The imaging of infrared night vision thermal imaging device will be based on temperature distribution. The higher the temperature, the brighter the brightness, while the lower the temperature, the darker the color. Its main purpose is to discover targets and identify target categories, such as humans, animals, etc.
2. The influence of lighting factors
1) The second-generation+night vision device is greatly affected by the environment due to its imaging principle. Especially under the influence of light, when the light becomes darker, the observation distance will be shortened. In the case of complete darkness, auxiliary infrared light sources must be used, and the distance of auxiliary infrared light sources is generally only up to 100 meters. At the same time, they also fear strong light, although many traditional night vision devices have strong light protection. But if the environmental brightness changes greatly, it will have a significant impact on the observation.
2) Infrared thermal imaging night vision device is not affected by light. Whether it's day or night, rainy, snowy, or foggy, the target object can be clearly observed. It is precisely for this reason that top of the line car night vision devices, such as Mercedes Benz and BMW, use infrared thermal imaging devices.
