Thermography is a technology that measures the surface temperatures of an object. This technology has been incorporated into diagnostic equipment used by medical professionals, devices that enable firefighters to see through smoke, and some night-vision equipment.

Thermographic images are taken with a thermal or infrared camera. Cooler areas appear blue and purple, while warmer areas appear yellow, orange, and red. Thermographic pictures of an animal can reveal areas that are excessively warm or cool—both indicating abnormalities and the need for closer evaluation.
