| Infrared thermography is one of the most recent and innovative techniques used by the DIAPReM research center in the non-inva-sive diagnostic imaging.Recently there has been a progressive interest in this technique in the construction, architecture and architectural heritage because it allows to obtain real-time images that can be acquired and evalua-ted in the presence of customers by providing decisive information instantly.Infrared thermography is intended as the graphical representation of the thermal state of an object or as a representation of the object surface temperatures. This is possible because all objects with temperatures above ab-solute zero emit and absorb infrared radiation to reach a thermal equilibrium. The thermal equilibrium depends on internal circumstances of the matter, on the situations of the external environment or both fac-tors.Since infrared radiation is not visible to the human eye, thermo-graphic analysis tools convert the infrared signal in video signal. They also combine a color scale to the scale of temperature. The thermographic image reading can be automatic or manual.Thermographic survey returns a real thermal image of an object is stationary, a moving object or an object placed at any distance. Thermography technique does not require any physical contact and does not affect the surface temperature and the morphology of the object. |  |
