Thermographic imaging is a relatively new field in Norway. However attention surrounding the use of thermographic imaging in various fields has increased in recent years. Thermography is a method of reading the temperature of a surface. This is performed with an IR-camera or thermal camera (see image), which is sensitive to infrared radiation. Thermography is a technology that, via the use of thermal cameras, measures temperature and shows an image of the object’s thermal energy. Thermal energy or infrared energy is light from a wavelength that cannot be detected with the naked eye. This wavelength is part of the electromagnetic spectrum (image to the left), which we detect as heat. All objects above absolute zero (- 273,15° C) generate heat and thus infrared radiation.

Even extremely cold objects, for example ice cubes, generate infrared radiation. An object generates more radiation the higher its temperature. Thanks to IR-technology, we can see what our eyes cannot detect. Using a thermal camera we can take images of invisible infrared radiation (heat) and measure the exact temperature without contact. As the thermal camera rapidly and simply gives an overview of the temperature conditions, it is a valuable tool within many areas.

It is used as a heat-detecting camera to cover areas that have abnormal temperature differences. It is used on both humans and animals. It is a good tool and is used as part of our diagnostic procedures.
