Infrared non-destructive testing (NDT) is a technique used to evaluate the properties of materials and structures without causing any damage. This method primarily utilizes infrared (IR) radiation to detect variations in temperature and thermal properties of the materials being inspected. Here are some key aspects of infrared NDT: ### Principles - **Thermal Radiation**: All objects emit infrared radiation based on their temperature. By measuring this radiation, one can infer surface temperatures and identify thermal anomalies.
