Thermal imaging is a technique that utilizes the infrared radiation emitted by an object itself to form an image. All objects, due to their temperature above absolute zero, emit an infrared spectrum of varying intensity, which is related to the temperature and material properties of the object. A thermal imaging camera captures this invisible infrared radiation by means of a built-in infrared detector and converts it into an electrical signal.

Each pixel on the detector corresponds to a different intensity of radiant energy received from the target object, which is converted into a corresponding voltage or current signal by the photoelectric effect. These signals go through a series of processes including amplification, digitisation and colour coded electronic circuit to map different temperature values into different colors to produce a visual thermal image.

On the thermal image, the colors represent the temperature distribution on the surface of the object, which can help users analyze the temperature difference and reveal the potential failure of equipment, environmental changes, the health status of organisms and other information, covering a wide range of applications such as industrial inspection, medical diagnosis, military reconnaissance and other fields.
