Electromagnetic Sensor Arrays for Nondestructive Evaluation and Robot Control.
Abstract
It has been demonstrated that small single-turn printed loops can be used as sensors with sufficient sensitivity to be useful in NDE and robotics and that printed-circuit techniques facilitate the fabrication of arrays of small loops to provide electronic scanning with high spatial resolution. It has also been shown that deconvolution techniques improve the spatial resolution of such sensors in detecting edges and slots. Future research plans under this contract include developing a model for inductive sensor arrays; designing and building a horizontal-loop array with vertical connections; demonstrating electronic scanning in one, and perhaps two, dimension; and exploring the possibilities of arraying drivers as well as sensors.
