Can infrared thermal imaging really see through walls?

Thermal imaging, as an important visual extension technology, is not affected by visible light and can see heat source objects in the dark. It can even penetrate dense smoke and fog and sense temperature differences. Therefore, thermal imaging is widely used in military, security, rescue and other fields. However, some people have misunderstandings about thermal imaging, thinking that thermal imaging can see through walls, which is incorrect.

In fact, thermal imaging cannot see through walls. This is because the walls we encounter in daily life are generally thick enough to effectively block the infrared radiation on the other side of the wall. Therefore, thermal imaging cannot see through the wall or see people through the wall. Infrared radiation is an important principle for thermal imaging to sense objects. If the wall is thick enough, then infrared radiation cannot penetrate the wall, and thermal imaging cannot sense objects on the other side of the wall. However, some smoke or haze can be penetrated, and even thinner ones such as plastic bags are no problem.

Thermal imaging is like human "heat-sensing eyes". It can capture the heat signals hidden outside visible light, allowing us to see the other side of things!

The applications of infrared thermal imaging are very wide! Engineers can use thermal imaging to detect leaks in homes and find the problem without tearing down walls! Moreover, if your home has floor heating installed, you can also use thermal imaging to detect it, quickly find possible hot or cold spots, and help you maintain the floor heating system to ensure warmth and comfort. In addition, infrared thermal imaging also plays an important role in the medical field. Infrared thermal imaging technology is used to diagnose and monitor diseases, such as breast cancer and infectious diseases. Medical infrared thermal imaging technology passively receives the metabolic heat source of human tissue cells and observes the shape and intensity of heat source distribution in the human body to achieve early screening of diseases, health assessment, etc.

In the future, with the continuous development of science and technology, thermal imaging will play a greater role in more fields such as agriculture, construction, environmental protection, and scientific research, bringing more convenience to our lives.
