To address this issue, this study develops a non-equilibrium sensing mode of enhancing electromagnetic field adjustments to balance the induction field due to an uneven distribution. Specifically, it builds upon differential eddy current probes by adaptively constructing Gaussian compensate distributed hollow-core copper coils with varied structural parameters, forming a receiving array that enhances the probe's discriminative ability as well as maintaining sensitivity. To strengthen the induced eddy current, the excitation coil is relocated from above the receiving coil to the same plane as the receiving coil array. This adjustment mitigates the sensitivity reduction caused by the resolution enhancement. A theoretical equivalent circuit model of the proposed method is established. Both simulation and experiments on vary defects in pipeline have been conducted to validate the reliability and efficiency of the proposed system.

To address this issue, this paper presents a defect localization method based on multipath edge reflected Lamb waves, which can be used for the SHM of square carbon fiber reinforced plastics (CFRP) laminates that have orthotropic material properties. Firstly, the feasibility of using edge reflections to detect defects in orthotropic materials is analyzed, laying the foundation for the construction of a multipath model. A modified dispersion compensation algorithm is then developed based on the equivalent dispersion relations, so as to minimize the influence of the orthotropic property on the signal waveform. On the basis, a four-step implementation process of the detection method is established, including identifying edge reflected wave packets, tracking theoretical virtual wave paths, matching wave packets with virtual paths, and imaging the detection area by fusing images of multipath wave packets. Experiments on three different defect cases show that the method can localize the defect on orthotropic CFRP laminates accurately, even its position is near the edges. Compared with the widely-used delay-and-sum algorithm, the method also performs better in the presence of strong edge reflections, thus can be an efficient SHM tool for the orthotropic CFRP laminates of small sizes.</div></div>","PeriodicalId":18868,"journal":{"name":"Ndt & E International","volume":"155 ","pages":"Article 103413"},"PeriodicalIF":4.1,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143806845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, traditional X-ray imaging methods struggle to achieve high sensitivity for pixel-level defects (1–3 pixels) in noisy or scattering-dominated environments, such as metal workpieces or thick low-Z materials. To address this, we introduce move contrast X-ray imaging (MCXI), which leverages relative motion between the sample and imaging system to suppress noise and enhance the sensitivity of weak signal detection in complex backgrounds. MCXI has been successfully applied in fields such as biomedical imaging and high-resolution material studies, demonstrating significant noise resistance and sensitivity improvements. This paper extends MCXI to the testing of defects in static samples, aiming to solve the challenges of detecting pixel-level in high-noise and complex backgrounds. Numerical simulations demonstrate MCXI's capability for single-pixel defect detection. Synchrotron radiation experiments validate this technique through quantitative characterization of 1.54-pixel defects (1-μm polystyrene spheres) in low-contrast polyvinyl chloride (PVC) samples, achieving a CNR of 26.12 - representing a 14.04 × improvement over direct projection imaging. The method's industrial applicability is demonstrated through alloy steel pipe testing with 81.2 μm defects (8.12 pixels), where MCXI achieves a CNR of 15.16 (8.1 × enhancement) using laboratory-based X-ray systems.
