At present, technology is constantly improving, and technological products are changing with each passing day. In recent years, infrared thermal imaging night vision devices have been widely used in the civilian field for natural observation, outdoor hunting, outdoor adventure, security and anti-theft, marine operations, night patrols and other occasions with an increasing trend! Infrared thermal imaging can see clearly in a completely dark environment and can clearly detect high-temperature targets due to its special performance principle!

I believe that many people are more concerned about whether thermal imaging can penetrate. The answer is: thermal imaging can penetrate! For example, plastic bags.

Thermal imaging can indeed penetrate this material. Infrared thermal imagers are not affected by low illumination and strong sunlight, and can penetrate smoke, haze, etc. However, thick clothes cannot be penetrated, so there is no need to worry about your privacy. Infrared thermal imagers realize the imaging of objects by collecting thermal radiation from different objects, so that they can be reflected less by certain materials than visible light, and can pass through thin fabrics and be reflected back by objects hidden under the fabric and pass through the fabric again, so that some special fabrics (pure nylon and silk) can be made translucent, but the perspective effect is relatively limited.

If clothes cannot be penetrated, then walls are even worse. Thermal imaging penetration in movies and games is all special effects plus plug-ins!

In summary: Thermal imaging can see through some materials, and choosing the right band can also allow you to see inside (such as in industrial medical applications). However, when encountering completely opaque objects such as walls, it is impossible to penetrate and observe them like using cheats in games.
