Planar electromagnetic inductance tomography (EMT), Image reconstruction.
Planar electromagnetic inductance tomography (EMT) may be used for non-invasive imaging of conductors embedded in a non-conducting medium. An example is the imaging of steel reinforcement bars in concrete structures from electromagnetic measurements on one surface only. Some preliminary work has been reported on the feasibility of using a planar array of sensor coils to image steel conductors embedded in a concrete structure. However, the results were based entirely on computer simulations. This paper takes the work one step further and demonstrates the feasibility of planar EMT for imaging ferromagnetic conductors based on measurements made on a prototype sensor array.
