What is infrared thermography?
Thermal imaging, also called thermography, is the production of non-contact infrared, or “heat” pictures from which temperature measurements can be made By detecting anomalies often invisible to the naked eye, thermography allows corrective action before costly system failures occur. Portable infrared (IR) imaging systems scan equipment and structures, theninstantly convert the thermal images to visible pictures for quantitative temperature analysis.
In simple terminology, infrared thermography is a graphical representation of heat. Everything around us is constantly loosing heat to the environment. We can feel heat, but we can not see it as infrared radiation is below the last visible color. We need a special camera to detect infrared and then display an image on a screen. The technique of detecting infrared heat is called infrared thermography.
Infrared Thermography is the technique for producing a visible image of invisible (to our eyes) infrared energy emitted by objects. The higher the temperature, the more energy emitted. The typical infrared thermography camera resembles a standard camcorder and produces a live TV image of heat radiation. The camera provides a basic grey scale image which is converted to false color images to make interpretation of thermal patterns easier. More cameras will also measure the temperatures of the target object. The thermal image produced by an infrared camera is called a thermogram.
Infrared Thermography is the technique for producing an image of invisible (to our eyes) infrared light emitted by objects due to their thermal condition. The most typical type of thermography camera resembles a typical camcorder and produces a live TV picture of heat radiation. More sophisticated cameras can actually measure the temperatures of any object or surface in the image and produce false color images that make interpretation of thermal patterns easier. An image produced by an infrared camera is called a thermogram or sometimes a thermograph.
