Thermography is a non-contact diagnostic technique that detects and visualizes infrared radiation emitted by an object. All objects above absolute zero emit thermal energy, and the intensity and wavelength of this radiation are dependent on the object's temperature. Thermography captures this emitted infrared energy and converts it into a visual image called a thermogram. Thermograms display temperature variations across a surface, often using a color scale where different colors represent different temperature ranges. This allows for the identification of hotter or colder areas that might not be apparent to the naked eye.

The technology relies on infrared cameras equipped with specialized sensors. These sensors are sensitive to the infrared spectrum, which is beyond the range of human vision. The collected infrared data is processed by software to create the thermogram. Applications of thermography are widespread. In industrial settings, it is used for predictive maintenance to detect overheating in electrical equipment, identify insulation defects in buildings, and monitor manufacturing processes. In the medical field, thermography can be used for assessing blood flow, detecting inflammation, and in some cases, as an aid in breast cancer screening. It is also employed in security for surveillance, in research for studying heat transfer, and in firefighting to locate the origin of fires and search for victims. The primary advantage of thermography is its non-invasive nature, allowing for assessment without physical contact or disruption.
