Lockin thermography is a reliable and fast NDT-technique that can be applied for a wide range of testing problems in aerospace applications. It is robust and sensitive enough to be used in industrial environments. Many different excitation methods based on specific physical mechanisms can distinguish between defective and intact material. Optically excited thermography, for instance, can detect boundaries, like delaminations, whereas ultrasound excited thermography is sensitive to inner friction and therefore defect-selective. The paper describes the principle of optically, ultrasound, and eddy-current excited thermography and presents several applications to typical aerospace structures.
