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.

Abstract: A method including ultrasonically scanning a structure with a laser ultrasound testing system where the structure is provided with an array of nanoscopic structures, the nanoscopic structures having a predetermined directional orientation, the nanoscopic structures disposed on a scanned surface of the structure, and determining if the structure meets a predetermined threshold. Aspects of this invention apply certain high emissivity coatings to structures for the purpose of significant improvement laser ultrasound inspection of those structures. The nanotechnology-based material in the coatings rapidly draws heat away, for maximum laser energy absorption while preventing surface heat damage to the composite surface from the laser beam.
