Non-Destructive Testing

Non-destructive testing
Tough, light and reliable materials are the key to many developments. Identification of defects, impurities or cracks in these materials is often crucial. X-ray imaging is a tool that has been used for these purposes for a long time. However, standard imaging technologies are often tuned for metals. Therefore, the traditional X-ray imaging systems fail in case of modern light materials such as composites. Our novel inspection technologies and photon counting detectors are ideal for this purpose.

Advanced NDT solutions

ADVACAM brings to the market a new range of X-ray imaging cameras that are optimized for composite material testing. Light materials such as carbon fibres, epoxies, etc. are easily revealed in a great detail. Even challenging defects such as deep laminate wrinkles, kissing-bonds, delaminations, porosity, foreign objects and micro-cracks in the soft materials can be detected with spatial resolution of 55 µm or better. Similarly to its application in biology, the sensitivity to low energies is useful for non-destructive testing (NDT). Combining the sensitivity to low X-ray energy photons with the very high dynamic range of photon counting detectors creates a powerful tool for NDT in airspace industry and elsewhere.
Contrary to the classical X-ray imaging setups, the robotic system produced by Radalytica s.r.o. gives nearly absolute flexibility of viewing angles. Therefore, these robots allow X-raying from different perspectives, to better localise defects. Moreover, robots further open possibility of using 3D imaging techniques such as computed tomography or tomosynthesis. These are methods commonly used in X-ray imaging, but with limited applicability on large complicated shapes. Robots help overcome this limit. The robotic systems could be used in quality control labs or built into production lines.
