False-colour thermogram of a hot steam iron,viewed from the side. Thermography is an imaging technique used to visualise heat distribution. This relies on the emission of long-wavelength infrared radiation by the object in proportion to its temperature. The radiation is detected electronically and displayed by intensity. Here,the temperatures are colour coded from blue (coolest) to white (hottest) according to the scale at right. The hottest part seen here is metal cladding around the base and the water reservoir. Note that the handle stays relatively cool | |
