Title: A Dual-Function Inductive Sensor for Imaging Steel, Corrosion Products and Graphite Based Materials

Abstract

An inductive sensor is described that combines both Q-detection and heterodyne technology. By exploiting the change in amplitude and frequency of the received signals, it may be used for imaging steel reinforcement bars, surface corrosion and, generally, materials with different permeability and conductivity ratios. Real time digital signal processing is used to improve the signal to noise ratio of the sensor and to provide a feedback stabilization mechanism for the reduction of long-term drift.
