ABSTRACT:
The porosity and integrity of a nonconductive material is determined using electron beams and electronic instrumentation. The electric corona discharge from holes in the nonconductive material is detected and analyzed in order to determine the presence of viral and sub-viral sized voids or holes, as well as other material anomalies such as blisters and bubbles.
