    摘要： An eddy current surface inspection array probe and method for detecting cracks and flaws in aircraft skin metal immediately surrounding rivets, without requiring rivet removal or manual scanning. The array probe includes a circular array of small sense coils positioned beneath a much larger drive coil encased in ferrite. The sense coils are differentially connected in pairs such that the signals from two sense coils located on opposite sides of the rivet (180.degree. apart) subtract to produce a resultant output signal. During operation, the probe is positioned concentrically over the rivet and data acquired from all sense coil pairs. If no cracks or other defects are present, all sense coil pairs produce a null (zero) signal. If a crack exists, some sense coil pairs (the exact number depending on the crack length, number of sense coils, and sense coil spacing) produce a non-zero signal. The probe and method can be employed to inspect a variety of other structural features which are nominally circularly symmetrical.

    摘要翻译： 一种涡流表面检测阵列探头和方法，用于检测立即围绕铆钉的飞机皮肤金属中的裂纹和缺陷，无需拆除或手动扫描。 阵列探头包括位于铁氧体内包围的较大驱动线圈下面的小感测线圈的圆形阵列。 感测线圈成对地差分连接，使得来自位于铆钉（180°）相对侧上的两个感测线圈的信号减去以产生合成的输出信号。 在操作期间，探头同心地位于铆钉上，并从所有感测线圈对获得的数据。 如果没有出现裂纹或其他缺陷，则所有感测线圈对产生零（零）信号。 如果存在裂纹，则某些感测线圈对（根据裂纹长度，感测线圈数量和感测线圈间隔的精确数量）产生非零信号。 探头和方法可用于检查名义上圆形对称的各种其他结构特征。

    摘要： A phase-difference eddy current imaging system has a bridge circuit including a pair of coils with one or both coils disposed proximate an object that may contain one or more flaws. An oscillator is coupled to the bridge circuit and also to a pair of phase detectors that are coupled to the coils. A differential amplifier is coupled to the phase detectors for providing a comparison signal. A method for eddy current imaging using phase difference detection comprises providing relative movement between an object and at least one of a pair of coils, measuring the phase of the effective reactance in each of the coils, comparing the measured values, and formatting the compared values as a function of spatial position.

    摘要： The invention discloses an inspection system for detecting near surface flaws or defects in conductors using nondestructive eddy current testing suitable for industrial application. The system provides a method and apparatus for acquiring real time, synchronized, discrete eddy current measurement signals from a plurality of sufficiently disposed, spatially correlated eddy current probes then processing and formatting said measurement signals automatically over parallel data channels to accommodate digital processing techniques in order to produce on eddy current image. Utilizing digital image processing provides a capability for improving flaw detection limits while simultaneously enhancing image resolution.
