ThermographyThermography is a type of infrared imaging. Thermographic cameras detect radiation in the infrared range of the electromagnetic spectrum and produce images of that radiation. Since infrared radiation is emitted by all objects at ambient temperature, thermography makes it possible to "see" one's environment with or without visible illumination. The amount of radiation emitted by an object increases with temperature, therefore thermography allows you to see variations in temperature, hence the name. With a thermographic camera warm objects stand out well against cooler backgrounds. Humans and other warm blooded animals become easily visible against the environment day or night. As a result historically the biggest users of infrared imaging have been the military and security services. The appearance and operation of a modern thermographic camera is often similar to a camcorder. Since they allow the user to see in the infrared spectrum they are still useful without the ability to record their output. As a result many thermographic cameras do not have an inbuilt ability to record. External links
