Aerial Thermography

Its use for the detection of the state of the structures is extremely useful in the field of renewable energy, such as in the detection of the energy dispersion in the form of heat.


Thermography is the acquisition of an image obtained by using infrared radiation (IR) emitted by a “hot” object. Analogously to the photograph which is obtained from the visible light reflected from an object, thermography is obtained thanks to the "light" IR that a body emits on the basis of its thermal state and that is of the distributed temperature point by point on the body itself. Since it this radiation is not visible, it is agreed to associate to each temperature detected on a specific object in a color chosen from a color scale corresponding to various temperatures.


Thermography therefore offers information not detectable with an ordinary camera, because it takes the thermal state of an object (and the temperature point by point), unlike a photo-shooting. It's easy to understand how technology IR had a big credit from the first years of appearing in various areas.


It appeared, however, not easy to approach because it requires special skills and solid experience on the specific application, at the end of a correct interpretation of the thermal images that are also connected to the types of materials with which the object under examination was made.


The relief of the thermal state of a simple object or a complex system, of a structure or of a more or less extended allows, through an analysis of the temperature gradients detected. to assess their status (physical, chemical, biological, etc.) and compare it with the natural order to identify changes induced by external causes. This analysis no destructive gives the possibility of examining objects, to monitor installations, to study processes, to verify modifications, changes or alterations determined by various factors. We show here results of the application of thermography photovoltaic systems: it is clear the economic advantage in the early detection of defects in parts more or less extensive modules installed.
