Infrared thermography operates by utilizing infrared radiation to measure the surface temperature of an object or material. The infrared light signal emitted by the object is converted into an electrical signal, yielding the spatial distribution of the surface temperature of the object through the output signal of the imaging device. Following appropriate processing, a thermal image corresponding to the surface temperature field of the object can be obtained (Lin et al., 2021). The spatial distribution of the surface temperature of the object is obtained through the output signal of the imaging device. Subsequent software processing enables the acquisition of a thermal image corresponding to the surface temperature field of the object. In instances where concrete specimens exhibit varying degrees of damage, variations in the surface temperature and infrared thermal image characteristics are primarily influenced by the thermal diffusivity α of the concrete under identical conditions. As such, the accurate measurement of the infrared radiation from the surface of an object is instrumental in determining its surface temperature, as well as inferring its material properties, internal structure, and surface state based on the intrinsic relationship between infrared radiation, surface temperature, and material properties.
