Does the thermal imaging night vision device have see-through function? Can the thermal imaging night vision device see people through walls?
1. What is a thermal imaging night vision device
The thermal imaging night vision device is a kind of infrared thermal imager, which is invented based on thermal imaging technology. It can be observed at night, and all objects that are not at absolute zero will emit electromagnetic radiation of different wavelengths, so it can A real-time image is generated by the external radiation emitted by the object at different temperatures, thereby providing a thermal image of the scene.
2. Does the thermal imaging night vision device have a see-through function?
When the thermal imaging night vision device was invented, it was considered that it is mainly used at night and in bad weather, so the thermal imaging night vision device has a certain perspective function. Because it uses thermal infrared rays, the imaging is not affected by strong light. Can penetrate haze, smoke, etc.
However, the perspective effect of the thermal imaging night vision device is relatively limited. It converts the infrared radiation energy of the detected object into the image we can see.
Reflected by some materials less than visible light, it can penetrate some thin and light clothes such as pure nylon or silk, but not thicker clothes.
3. Can thermal imaging night vision go through walls to see people?
The thermal imaging night vision device can amplify the thermal radiation signal and convert it into a video signal through the detector and image video system, and let people see it through the display. Many friends are worried that others can see the indoor scene through the wall through the thermal imaging night vision device, invading people's privacy, so can the thermal imaging night vision device penetrate the wall?
The thermal imaging night vision device uses thermal infrared rays to work. Thermal infrared rays are penetrating, so they can observe the front in the dark night, and can penetrate fog, haze, rain, and snow. However, for walls, thermal imaging night vision The instrument is useless, thermal infrared rays cannot pass through opaque walls, and cannot see through the walls to see the situation inside; and the imaged picture is infrared, the hotter the place, the brighter the image, and the scene you see is completely different from usual, so don’t use it Worried that thermal imaging night vision devices will invade people's privacy.
