The Effects of Infrared Radiation on Temperature

infrared is the region of the spectrum, that humans and other animals mostly emit light as a result of our intrinsic temperature. This is why thermal imaging techniques work, because they don't detect visible light,. They detect mostly infrared light, and that is emitted by objects like humans. In a sense, the way we see the sun is the way Thermal vision sees us. It sees the light that is emitted because of the temperature of that object, not light that's reflected off the surface.
