Claim Text:
1. A sensor device capable of detecting changes in a target material comprising: a transmit coil being tuned to a desired resonant frequency by inducing an oscillating electromotive force for creating an oscillating magnetic field at the desired resonant frequency, the oscillating magnetic field being configured to propagate into the target material; a receive coil receiving the oscillating magnetic field with a resonant frequency which is in proximity to the desired resonant frequency of the transmit coil such that the output signal of the receive coil is improved for desired detection of features, flaws, and conditions of the target material; and a rotating member, the transmit coil and receive coil being mounted on the rotating member, the rotating member being rotatable to move the transmit coil and receive coil through an arcuate path about the target material; wherein the rotating member is mounted to a translating table, the rotating member rotating about an axis, the translating table being movable in a linear direction along the axis, the rotating member being translated along the axis with the translating table.
