Infrared thermography is equipment or method, which detects infrared energy emitted from object, converts it to temperature, and displays image of temperature distribution. To be accurate, the equipment and the method should be called differently, the equipment to be called as infrared thermograph and the method to be called as infrared thermography.
Advantage of thermography
It is non-contact – uses remote sensing.
It keeps user out of danger while scanning live electrical components
Targets at very high position can also be detected
