This article provides an in-depth analysis of the X-ray detectors used in Non-Destructive Testing (NDT), starting from the simplest technologies such as radiographic films and scintillators, up to the most innovative systems including solid-state detectors, perovskite sensors, and photon counting detectors.
The physics underlying their operation is explored, followed by an overview of applications in industrial, medical, aerospace, security, and cultural heritage fields.
Significant attention is devoted to emerging technologies such as superconducting nanowire detectors (SNSPDs), free electron lasers (XFELs), and artificial intelligence for automated analysis.
The article concludes with reflections on the technical challenges and future prospects of X-ray detectors in improving precision, reliability, and automation in NDT.
