摘要：

The applicability of noncontact analysis methods to the detection of rust in coated steel plates used for outdoor equipment has been examined. Reflection intensity measurements from a sample coated with epoxy resin show that optical coherence tomography using near-infrared (IR) light and THz waves can detect the hidden rust region, since near-IR light and THz waves can pass through the coating. This region can be reproduced by so-called THz imaging without contact. In contrast, neither X-ray fluorescence nor Fourier transform infrared spectroscopy can detect the rust, because of the strong X-ray and IR absorption peaks of the coating.
