Can thermal cameras see underground?

No, thermal cameras cannot see through underground. If you own a thermal camera smartphone, you can use it to try right now. Thermal cameras work by detecting the infrared radiation emitted by objects. This radiation is invisible to the human eye, but it can be detected by thermal cameras. The amount of infrared radiation emitted by an object depends on its temperature. Hotter objects emit more infrared radiation than colder objects.

When a thermal camera is pointed at an object, it creates an image that shows the different temperatures of the object. This image is called a thermal image. The thermal image can be used to see the hot and cold spots on the object.

However, thermal cameras cannot see through objects. The infrared radiation emitted by an object is blocked by the object itself. This means that a thermal camera cannot see what is behind an object.

In some cases, thermal cameras can be used to detect underground objects. For example, thermal cameras can be used to detect underground pipes that are leaking. The leaking pipes will emit more infrared radiation than the surrounding soil. This difference in temperature can be detected by a thermal camera.

However, thermal cameras cannot see through underground objects very well. The amount of infrared radiation that is emitted by an object decreases as the distance between the object and the thermal camera increases. This means that thermal cameras can only detect underground objects that are relatively close to the surface.

Overall, thermal cameras cannot see through underground. However, they can be used to detect underground objects that are relatively close to the surface.
