  This work introduces a novel Augmented Reality (AR) approach to visualize
material data alongside real objects in order to facilitate detailed material
analyses based on spatial non-destructive testing (NDT) data as generated in
X-ray computed tomography (XCT) imaging. For this purpose, we introduce a
framework that leverages the potential of AR devices, visualization and
interaction techniques to seamlessly explore complex primary and secondary XCT
data matched with real-world objects. The overall goal of the proposed analysis
scheme is to enable researchers and analysts to inspect material properties and
structures onsite and in-place. Coupling immersive visualization techniques
with real physical objects allows for highly intuitive workflows in material
analysis and inspection, which enables the identification of anomalies and
accelerates informed decision making. As a result, this framework generates an
immersive experience, which provides a more engaging and more natural analysis
of material data. A case study on fiber-reinforced polymer datasets was used to
validate the AR framework and its new workflow. Initial results revealed
positive feedback from experts, in particular regarding improved understanding
of spatial data and a more natural interaction with material samples, which may
have significant potential when combined with conventional analysis systems.
