False-colour thermogram of a hot coffee mug. 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 coffee mug seen here has contained hot water for some time,as the heat has permeated to the surface. Note that the handle (right) is still cool | |
