“Thermal imaging is a technique using a special camera that detects heat radiation from the objects in focus and converts then into images according to the infrared spectrum. A warm body or object emits enough heat that when placed against a cooler object, shows different colors in the screen. The hottest objects will appear white or bright colors, and black is emitted in low-temperature objects.” Renewable Energy SourcesJeremy FeakinsThermal Energy Author:jeremyfeakins
