Three-dimensional infrared thermography of buried defects from multi angle long pulse thermography

, 2023
Heat diffusing from the bulk of an object manifests at the surface of an object due to variations in structure and materials, which can give rise to thermal property variations. This allows for detection of defects, their size, shape, and location within an object.
