(4A10.90) Thermal Camera
A thermal camera is a device that creates an image using infrared radiation. Generally speaking, the higher an object’s temperature, the more infrared radiation is emitted. This device can still produce an image in total darkness since it is not searching for ambient light. Most infrared light does not go through glass, but can easily go through, for example, a black trash bag, which can make for a neat trick for the classroom.
