电磁方法如涡流技术不提供图像，而只是在难以理解的测量平面中产生局部信号。产生与X射线相媲美的图像的试验大多基于昂贵且耗时的机械表面扫描。本文介绍了用于涡流检测的模块化探头阵列的理论和实验步骤。与其他尝试相反，这些阵列在低频下工作，能够穿透静止的蜜蜂，并提供良好的横向分辨率。通过这种方式，它们不仅带来了表面缺陷，而且还带来了隐藏的缺陷，如下面0.5 mm的1 mm孔隙。潜在的工业应用进行了概述。（C）2011年机械工程杂志。All rights reserved.
Electromagnetic methods like eddy current technique do not provide images but merely produce local signals in a difficult-to- understand measurement plane. Trials to generate images comparable to x-rays are mostly based on costly and time consuming mechanical surface scanning.The paper presents theoretical and experimental steps ahead to modular probe arrays for eddy current inspection. In contrary to other attempts, these arrays work at low frequencies able to penetrate below the still bee and provide good lateral resolution. In this way, they bring up not only surface defects but also hidden defects like 1 mm pores with 0.5 mm underlying. Potential industrial applications are outlined.
