text: Since infrared radiation is emitted by all objects based on their temperatures, according to the black-body radiation law, thermography makes it possible to "see" one's environment with or without visible illumination.
text: Thermography is a technology that allows cameras and other equipment to pick up infrared light emitted by an object in the form of heat.
text: Infrared (IR) is the heat that is emitted by every object whose temperature is above absolute zero, which is about minus 460 degrees Fahrenheit or minus 273 degrees Celsius.
text: Unlike visible light though, infrared light is emitted by any object that has a temperature above absolute zero.
text: Infrared radiation is emitted by any object that has a temperature (ie radiates heat).
text: Since infrared radiation is emitted by all objects with a temperature above absolute zero according to the black body radiation law, thermography makes it possible to see one's environment with or without visible illumination.
text: Thus Infrared radiation is emitted by all objects in the room and we feel the warmth.
text: Some IR sensors detect objects' temperatures by measuring the amount of infrared radiation that is naturally emitted by the objects.
text: This is because infrared light is emitted by objects cooling off in the dark, and the wavelength of light is so long that it disperses quickly and tends to be absorbed by anything nearby, which generates heat.
