Abstract: The present disclosure provides for characterizing internal structures via ultrasound by inducing an ultrasonic test wave in a component; developing a test signature based on measured propagation of the ultrasonic test wave through the component; characterizing an internal feature of the component based a comparison between the test signature and a baseline signature for the component; and providing an indication of the internal feature as characterized. In some aspects, the ultrasonic test wave is induced by a laser inducer and/or received by a laser interferometer. The test signature includes one or more of: frequency responses, amplitude responses, and times of flight. The test signature can be used to identify changes in a component over time, verify similarity between different components, monitor thermal processes, and verify an identify of a component.

Abstract: A non-destructive inspection apparatus includes a robotic device, an end effector coupled to the robotic device, and a controller coupled to the robotic device and the end effector. The controller is configured to determine, based on an amount of linear actuator extension of a sensor of the end effector and an amount of rotation of the sensor about a first axis of rotation and a second axis of rotation, a displacement of the sensor relative to a center point of the end effector surface so as to determine location information of the sensor, wherein sensor data for a location on a surface of a test article is sensed and correlated with the determined location information of the sensor. The robotic device controls movement of the end effector and is configured to determine, during the movement of the end effector, positional information for the center point of the end effector surface.
