摘要： A method of assembling an eddy current probe for use in nondestructive testing of a sample is described. The method includes positioning at least one substantially planar spiral drive coil within the eddy current probe, such that the drive coil is at least one of adjacent to and at least partially within a flexible material. The method further includes coupling at least one unpackaged solid-state magnetic field sensor to the at least one drive coil.

摘要： An eddy current (EC) probe for inspecting a component is provided. The EC probe includes a tangential drive coil configured to generate a probing field for inducing eddy currents in the component, where a portion of the eddy currents are aligned parallel to an edge of the component. An axis of the tangential drive coil is aligned parallel to a surface of the component. The EC probe further includes a pair of sense coils, where an axis of the sense coils is aligned perpendicular to the surface of the component. The sense coils are configured to sense the portion of the eddy currents aligned parallel to the edge of the component.

摘要： An omnidirectional eddy current (EC) probe includes at least one EC channel having a first and a second sense coil that are offset in a first (x) and a second (y) direction and overlap in at least one of the directions (x,y). At least one drive coil is configured to generate a probing field for the EC channel in a vicinity of the sense coils. An omnidirectional EC inspection system includes an omnidirectional EC array probe (ECAP) that includes a number of EC channels and drive coils. Each EC channel includes first and second sense coils with opposite polarities. The drive coils have alternating polarities. Electrical connections perform differential sensing for respective EC channels. Corrective drive coils are disposed at respective ends of the EC channels and generate probing fields. An eddy current instrument is connected to the omnidirectional ECAP and receives differential sensing signals from the EC channels.
