Thermal Imaging Cameras Bring Visibility to the Spectrum
Thermal imaging devices and cameras can make heat energy visible to the human eye. This allows for complete analysis of the environment or an object. The thermal image produced by these devices is a thermogram. The highly-sophisticated technology behind thermal cameras allows heat signatures to be reproduced in a format that features in the visible spectrum of light. Thermal imaging cameras do not indicate a single temperature for an object, rather they reflect temperature variations from cold through hot and display them in a spectrum of colours. As human beings, our vision is limited to visible light on the electromagnetic spectrum. However, this is but a small portion of all light that is available on the spectrum. A much greater percentage is infrared radiation, the spectrum of light that requires specialized thermal imaging cameras.
