Simultaneous Measurement of Multilayered Composites,
Abstract
A theoretical treatment of the eddy current problem involving a two-layered conductor laminate is presented for a rectangular cross section coil, with experimental eddy current measurements indicating that a frequency of 1.5 MHz should be used to measure a 6.45 um aluminum conductor, a 0.5 MHz frequency should be used to measure a 50.8 um aluminum conductor, and a frequency of 30 MHz should be used to measure lift-off. The schematic and the basic design of a two-frequency microprocessor controlled eddy current system is also presented. (AN)
