Hair dryer. Thermogram of the heat distribution over the diffuser attachment of a hair dryer, showing variation in temperature over its surface. The temperature scale runs from white (warmest, 120 degrees Celsius) through red, yellow, green, blue and mauve to black (coldest, 20 degrees Celsius). Thermography is a technique for visualising the temperature of surfaces by recording their emission of long-wavelength infrared radiation. This heat radiation is detected electronically and displayed as colour variation, different colours representing different temperatures. | |
