< Set-up and components of robotic pulse-echo laser ultrasonic testing system >
Robotic pulse-echo laser ultrasonic testing system allows for inspection of complex composite structures with various curvatures, and it is designed to automatically generate inspection paths and detect defects based on data extracted from the three-dimensional information of the inspection target.
< Inspection results of Gaussian curvatures >
To validate the applicability of the developed system's configuration, a testing of the algorithm that deals with inspection path generation was conducted using Gaussian curvatures.
< Inspection results of 3D-printed control surface of unmanned aerial vehicle >
Ultimately, scan path were implemented using control surfaces for unmanned aerial vehicles, visualizing defects occurring during the continuous fiber 3D printing process.
Further research is underway to implement an algorithm that robustly generates inspection paths utilizing the shape information of inspection target
