Imaging Techniques

In this chapter we apply the accurate asymptotic formulae derived in Chap. 7 for the purpose of identifying the location and certain properties of the shape of the anomalies. We also discuss time-domain imaging of small anomalies. We restrict ourselves to conductivity and electromagnetic imaging and single out simple fundamental algorithms. Based on the asymptotic modeling in Sect. 7.4, these algorithms can be extended in the context of elastic imaging to detect the location and the EMT of a small elastic anomaly.
