An adhesive bond test resonance array provides inspection of adhesively bonded composite laminate structures with improved productivity and higher reliability. A holder has multiple slots arranged in a two-dimensional array for holding transducers in respective slots. The holder is adapted to position a probe end of each of the transducers adjacent a component for scanning and has a material hardness adapted for enabling flexing while scanning curved composite parts. A fluid channel is adapted for delivering a couplant to the probe end of the transducers such that the couplant is automatically delivered during scanning of the component to inspect bond integrity.

A nondestructive system and method for measuring non-conductive coating thickness is disclosed. The method includes providing a composite substrate, placing a conductive layer over a surface of the composite substrate, and depositing a plurality of non-conductive coating layers over the conductive layer. An eddy-current measuring coil formed on a printed circuit board is provided atop the coating layers. The coil has a driving trace with first and second driving electrodes, and a receiving trace having first and second receiving electrodes. The receiving and driving traces can be either coaxial or interwoven, are spaced apart, and share a common center. A load administered to the first and second driving electrodes using an eddyscope is measured across the first and second receiving electrodes to determine impedance; the measured impedance is used to determine a total thickness of the plurality of coating layers and whether an overall coating thickness is uniform.

A method and an apparatus for inspecting parts for surface contamination including the steps of covering the part with a film of water, and then scanning the wetted part with a infrared camera to preserve the reflected image of the reflected infrared light thereby defining a water break area of contamination.
