Man holding up a sheet of black plastic

A man holding up a sheet of black plastic. This image has a corresponding visible light image. This plastic is opaque to visible light, but is transparent to far-infrared light. This is in contrast to the man's glasses which are opaque to the IR light. This image was taken inthe far-infrared. The different colors represent different temperatures on the object. The lightest colors are the hottest temperatures, while the darker colors represent a cooler temperature. Thermography uses special cameras that can detect light in the far-infrared range of the electromagnetic spectrum (900?14,000 nanometers or 0.9?14 µm) and creates an image of the objects temperature..
