Do you know? With the development of the times, night vision technology has become a very important part of the current monitoring technology field. As a very professional device, night vision devices can be seen in various fields, and different types of products have their own advantages.
For example, in the field of long-distance night vision monitoring, the more commonly used night vision devices are laser night vision devices and infrared thermal imagers. Some people are confused about these two devices, so which night vision device is better? How should we choose the right product? This issue will give you a popular science about the main differences between thermal imaging and laser night vision devices.
First of all, laser night vision devices are actually a kind of active infrared night vision technology. Its basic principle is to diffuse the light source of the laser point through optics to achieve the purpose of night lighting.
Unlike laser night vision devices, infrared thermal imagers are a kind of passive infrared night vision technology. Its basic principle is to detect and absorb the infrared radiation of the target object, and at the same time convert it into infrared thermal imaging that can be seen by our naked eyes through means such as photoelectric conversion and signal processing.
Secondly, the image displayed by the laser night vision device can distinguish people and targets, allowing us to see the monitored objects more intuitively, while the image displayed by the infrared thermal imager can only see the approximate outline of the corresponding people and targets. From this feature, the laser night vision device is better.
Furthermore, the target range monitored by the laser night vision device is smaller, while the target range monitored by the infrared thermal imager is larger, so from this perspective, infrared thermal imaging is more advantageous.
The last difference is that the laser night vision device has a disadvantage, that is, the laser cannot penetrate the fog at night and is greatly affected by external effects, while the infrared thermal imager can penetrate dust, smoke, etc., and is less affected by external effects. Therefore, it is better to choose infrared thermal imaging when it is greatly affected by external effects.
So for the specific choice of these two devices, we need to consider what occasions they are used in, what effects we want to achieve, and make choices based on the differences in the functional characteristics of the two. Of course, in addition to performance characteristics, you must also consider your budget appropriately.
And, do you know? Lasers are not only used in the field of long-distance monitoring, but are also widely used in various fields, such as marking, drilling, measurement, diagnosis, etc. It is a key supporting technology for the development of high-end precision manufacturing. The demand for laser technology in industrial manufacturing, medical care, aerospace and other fields is increasing day by day.
