Thermal Shadow

Description: A man's foot was placed flat on a wooden surface for about 30 seconds. After the foot was removed, the surface remained warmer than its surroundings and kept the thermal imprint, or "shadow," for some time. Thermography is a technique for visualizing the temperature of objects by recording the thermal emission at infrared wavelengths. This image was acquired with a specialized camera that uses a focal-plane array of vanadium oxide microbolometers as a sensor. It is sensitive to electromagnetic radiation in the wavelength range of 8 to 14 micron. The camera produces a 320x240-pixel image where different colors correspond to different temperatures.
