Can the mirror really see through?

Infrared perspective is divided into night vision device and thermal imaging device. Night vision devices are generally used to monitor objects at night, such as infrared monitors, while thermal imaging is to see through objects according to the difference of surface temperature. For clothes, because of the different body surface temperatures, you can see the general outline of the human body, but you can't see the body parts clearly. So it is unscientific to say that infrared glasses can see through the human body.

The reason why we can see the surrounding scenery is because the light emitted by the light source shines on the object, is reflected to the naked eye, and is processed by the optic nerve to produce an image.

But our naked eyes can only feel visible light, but we can't feel infrared rays, ultraviolet rays, X rays and other rays. Night vision camera can see objects in the dark because it can receive near infrared rays, which are processed by photosensitive element CCD and converted into images that can be seen by our naked eyes.
