Thermal Infrared (TIR) scanner systems are important remote sensing instruments used to detect and measure thermal energy emitted by objects and surfaces. Unlike visible and near-infrared sensors that mainly record reflected solar radiation, TIR sensors detect emitted radiation, generally in the wavelength range of about 3–14 µm. Based on the platform on which they are mounted, TIR scanner systems are broadly classified into airborne and satellite-based systems. Both provide valuable information about surface temperature, thermal characteristics and environmental conditions. Airborne TIR scanner systems are mounted on aircraft and collect thermal infrared data while flying over a selected area. The scanner uses detectors that measure the thermal radiation emitted from the Earth’s surface and converts it into electrical signals, which are then processed to produce thermal images. Airborne systems can operate at relatively low altitudes and therefore provide high spatial resolution. They are particularly useful for detailed surveys of small or medium-sized areas. Aircraft can also be directed to specific locations, making airborne TIR scanning highly flexible. A major advantage of airborne TIR scanners is their ability to acquire detailed information about temperature variations. They are used for geological mapping, soil moisture studies, mineral exploration, forest
