Book excerpt: The objective of this research program was to develop the theoretical models, design methodology, and technology needed for optimally applying near field electromagnetic sensor arrays to nondestructive evaluation (NDE) and robot control. This program was a collaborative effort by SRI International and Stanford University. This report summarizes SRI's contribution to the program's third-year research activities. SRI's work on this study has shown that small printed circuit single turn loops exhibit good sensitivity when used as sensors. This technology allows ready fabrication of high resolution arrays. By addressing different elements in the array and suitably processing the resulting signals, different sensing functions can be realized with the same array. In particular, SRI has demonstrated the use of such arrays for edge tracking and ranging (proximity sensing).
