在本章中，各种探头配置讨论的背景下，他们是非常适合的特定应用。常见的和更奇特的配置包括在内。实际上，探头通常由一个以上的线圈组成，或者用于在缺陷检测中特别有效的差分操作，或者使得每个线圈可以针对其作为驱动线圈或拾取线圈的角色进行单独优化。有些探头采用混合设计，其中驱动线圈在试件中感应涡流，但信号由另一种类型的传感器测量，例如，霍尔器件或巨磁阻（GMR）传感器。薄，灵活的线圈设计的原位结构健康监测，和阵列探头设计的快速广域检查，也提出了。
In this chapter, various probe configurations are discussed in the context of particular applications for which they are well suited. Common and more exotic configurations are included. Practically speaking, probes are often composed of more than one coil either for differential operation that is particularly effective in defect detection or so that each coil may be individually optimized for its role as drive or pick up coil. Some probes are of hybrid design, in which a drive coil induces eddy currents in the test-piece yet the signal is measured by another type of sensor, e.g., a Hall device or a giant magnetoresistive (GMR) sensor. Thin, flexible coils designed for in situ structural health monitoring, and array probes designed for rapid wide-area inspection, are also presented.
