company news about How to choose thermal imaging and night vision goggles?

Thermal imaging night vision is also a kind of night vision device, but thermal imaging is very different from ordinary night vision devices! Thermal imaging is based on the passive reception of infrared energy radiated by everything above absolute zero! The detected infrared is defined and imaged according to the intensity of radiation of different objects with different temperatures. Various display modes, including common white hot, black hot, false color, etc.!

The night vision device takes the initiative to receive and image. The night vision device must have an external light source that shines on the object and reflects it into the night vision device to receive the image. The night vision device gathers the existing ambient light (starlight, moonlight or infrared light) through the front lens. This light, which consists of photons, enters a photon cathode tube, which turns the photons into electrons. The electrons are then amplified to larger quantities by electronic and chemical processes. The electrons are then projected onto a screen, which turns the magnified electrons back into visible light, seen through the eyepiece.

The advantage of thermal imaging is that it can clearly display targets with large temperature differences. It can be seen far away. It can also be used in a completely dark environment. It can penetrate smoke, and strong light has no effect on thermal imaging. The disadvantage of the night vision device is that it cannot see far, and it needs supplementary light in a completely dark environment, so it cannot recognize camouflage.

I believe that with the comparison of the advantages and disadvantages of thermal imaging and night vision devices, you probably already know how to choose. One is the purpose, and the other is the price. These two are the key points. Of course, the product that combines the two together is the best choice!
