Thermography is the observation, measurement and recording of heat. All materials on earth emit heat energy in the infrared portion of the electromagnetic spectrum; the quantity of infrared heat emitted is directly comparative to its temperature. The human eye cannot see in the infrared unaided but by using Thermography and thermal images users can see thermally, observing anomalies that in turn identify problems. Modern infrared cameras view not only in real-time, but can also record infrared images and measure the temperatures of target objects quite accurately—to within 0.1 °C or better. Areas for investigation are displayed as hot or cold in relation to their surroundings. |
