There is another type of night vision goggles, which uses thermal imaging to make night vision possible. This kind of night vision goggles use the heat of electro-magnetic radiation, which is emitted by most objects, be they living or non-living. Because of this, thermal imaging night vision goggles are able to use these heat signatures in order to display an image of the object. Read more information for making Night Vision Goggles.
