The Principle Of Why Infrared Cameras Can See Through

Infrared perspective photography is the use of infrared rays to shoot scenes that cannot be seen by the naked eye, especially when shooting in a completely dark environment. The principle is basically the same as ordinary photography. The only difference is that infrared night scene photography uses infrared rays that are invisible to the naked eye as the lighting source. Take the shot.

Because the wavelength of infrared light is longer than that of visible light, it is less reflected by certain materials or textile fabrics than visible light. In this way, infrared light can penetrate clothes made of some materials and reach objects hidden under the clothes (such as the body). ) and then reflect back, thus making the clothes translucent and giving the body an almost naked effect.

However, not all clothes can be seen through infrared light. Pure cotton clothes cannot be penetrated by infrared rays, so they are the safest. Nylon and cotton-blend fabrics may be see-through, especially wet clothes in swimming pools and other places, where the see-through becomes clearer.
