Human hand,thermogram. A thermogram shows the variation in temperature on the surface of an object,measured by the long-wave infrared radiation it emits. The temperature scale is colour-coded and runs from purple (coldest),through blue,green,yellow and orange to red (warmest). In cold conditions,the human body reduces blood flow to the extremities,causing them to feel cold | |
