Patent ID: 7948233

Claim:
An omnidirectional eddy current array probe for detecting one or more flaws in a conductive test object, comprising: a first row comprising a first drive line disposed in a first layer having a first wave pattern with a first peak and a first trough operative to induce a first eddy current in the conductive test object, and a second drive line disposed in a second layer having a second wave pattern with a second peak and a second trough operative to induce a second eddy current in the conductive test object, wherein the first drive line is shifted from and superimposed over the second drive line, wherein the first and second drive lines are multiplexed; at least one additional row identical to the first row, wherein the at least one additional row is offset from the first row arranged such that the wave patterns of the first row complements the wave patterns of the at least one additional row; and a sensing portion disposed proximate to the first and second drive lines of the first row and the at least one additional row operative to sense the eddy current in the conductive test object and output a signal indicative of the sensed eddy current.
