Sensor Placement via Optimal Experiment Design in EMI Sensing of Metallic Objects

Figure 9

SED experiment with the MPV, three-object example. Initial sounding (S1): (a) the sensor footprint (black circle) and inverted two-object locations (small circles); (b)-(c) recovered polarizabilities with a two-object model; (d)–(f) recovered polarizabilities with a three-object model. Soundings S1 + S2: (g) the sensor footprint and inverted two-object locations; (h)-(i) recovered polarizabilities with a two-object model; (j)–(l) recovered polarizabilities with a three-object model. Recovered polarizabilities are in blue, red, and black and the reference ones in gray dashed.
