ABSTRACT:
Inconsistencies in a resin-based part are detected using a capacitive coupling probe having a tuned circuit and an impedance matching element. An alternating electric field produced by the probe penetrates the part. Inconsistencies in the resin part result in changes in the resonance of the circuit which are detected by a network analyzer.
