“…More recently, the small form factor of many solid-state magnetic field sensors has been investigated for high-resolution imaging using scanned sensors or high-density sensor arrays [4,5]. In one such example a two-axis orthogonal magnetoresistive sensor based eddy current probe developed by our group was shown to isolate features separated by as small as 250 m while also measuring stray DC magnetic fields with sub-mOe resolution [5,6]. Continued work on this sensor platform has resulted in increased functionality through a redesign of the induction wire path.…”

Numerical design of outer diameter remote field eddy current probe for the inspection of nuclear fuel rod AIP Conf. Proc. 557, 953 (2001); 10.1063/1.1373859Simulation and design of a superconducting eddy current probe for nondestructive testing Rev.Abstract. The incorporation of magnetic field sensors into eddy current probes can result in novel probe designs with unique performance characteristics. One such example is a recently developed electromagnetic probe consisting of a twochannel magnetoresistive sensor with an embedded single-strand eddy current inducer. Magnetic flux leakage maps of ferrous materials are generated from the DC sensor response while high-resolution eddy current imaging is simultaneously performed at frequencies up to 5 MHz. In this work the design and optimization of this probe will be presented, along with an application toward analysis of sensory materials with embedded ferromagnetic shape-memory alloy (FSMA) particles. The sensory material is designed to produce a paramagnetic to ferromagnetic transition in the FSMA particles under strain. Mapping of the stray magnetic field and eddy current response of the sample with the hybrid probe can thereby image locations in the structure which have experienced an overstrain condition. Numerical modeling of the probe response is performed with good agreement with experimental results.
