With the parameters, a relationship is derived to calculate the sensitivity of the magnetic flux guide in the eddy current measurement system. The relationship will used to optimize the configurations of the sensing part of the system in design stage. It is also experimentally shown that shielding the magnetic flux guide will help to increase the spatial resolution in the system.
