A thermal imager is used to detect radiation (heat) originating from an object, convert it to temperature, and display an image of the temperature distribution. This process is known as infrared thermography. Thermograms—illustrations of the detected temperature distribution—allow the observation of heat-producing objects that are invisible to the unaided eye. It is extensively utilized in building diagnostics, medical imaging, law enforcement, and security imaging, as well as predictive maintenance and condition monitoring.
