WebEmissivity is a measure of how efficiently an object radiates heat, i.e. how well the surface of an object “tells the truth” about its temperature. Emissivity values range from 0 (a theoretically perfect mirror that reflects all energy) to 1 (a theoretical object called a blackbody that perfectly absorbs and radiates all energy). Notice that the emissivity … Web9. sep 2016 · Thermography (IR thermal imaging), is a method of a non-contact temperature measurement using a temperature-calibrated IR camera. Thermal energy detected by IR cameras is not visible to the human eye, so the different temperatures in a thermal image may be "mapped" to different colors for display using IR visualization software (Figure 2).
