The flexible eddy-current probe array concept, which was                        developed by Failure Analysis Associates, allows coverage of the                test area without scanning, by placing an array of probes,                      fabricated on a thin flexible substrate, against the test surface               and electronically multiplexing through the array elements in a                 selected sequence.  The goal of this project is to advance the                  flexible eddy-current array concept to a position of practical                  utilization.  The application of holographic inversion of the                   data obtained from stacked, staggered arrays will be explored in                order to improve the resolution.  A closer packing of the                       elements is obtained by a matrix electrical interconnection                     scheme.  This involves a matrix inversion operation to extract                  the individual element response from the mixed signal of the                    entire array.  The algorithms developed in the course of this                   project will be incorporated into software that will run on a PC-               based eddy-current instrument.
