Abstract : Defects and irregularities in fiberglass-aluminum honeycomb structures are visually displayed by ionization corona formed by a relatively high potential on a conductive mesh screen contained in transparent dielectric hand-held probe. Both the frequency and the amplitude of the potential are controllable by hand operated controls on the probe to provide optimum electrographic images in the ionization of the air in the interelectrode gap between the probe electrode and the structure being examined.
