Nondestructive evaluation (NDE) techniques have evolved over the years, but the fundamental process of interpreting data from sensors remains challenging due to cognitive overload on inspectors. Although 3D visualizations are currently used in complex scenarios, such as defense and aerospace, they have yet to become mainstream in NDE processes. Firms like Extende and EPRI are developing inspection simulators using Augmented Reality (AR), Virtual Reality (VR), and Extended Reality (XR) technologies for training inspectors in NDE techniques.

Digital visualization presents numerous opportunities for NDE, including AR and VR for inspector training, which address key challenges such as the lack of hands-on practice and fear of failure. Telepresence enables experts to assist field inspectors remotely during complicated procedures, while visualization of NDE data in a browser allows for improved accessibility and integration with digital twin systems. Additionally, XR-based simulators can mimic inspection equipment and data capture processes, training inspectors in real-life situations they might encounter in the field.

Visualizations are an emerging field with a significant potential impact on the future of NDE. As technology advances, more complex and dimensional visualizations may become possible, enabling better understanding of defects and their propagation over time. This could lead to enhanced product design, failure prediction, and overall improvement in NDE practices.
