Suppose that M7_BisonCeseriFasinoInglese0.png is a thin conducting plate whose top side is not accessible and stays in contact with an aggressive environment. In this context, possible damages on the top side of M7_BisonCeseriFasinoInglese0.png are produced with no chances of direct fast detection. Anyhow, we are able to control a periodical heat flux and to collect a sequence of temperature maps working on the bottom side (accessible). In this paper we test a stable numerical algorithm for detecting and evaluating such damages on the inaccessible side of M7_BisonCeseriFasinoInglese0.png. Our algorithm is based on the regularized solution of a family of inverse problems for Helmoltz equation. [DOI: 10.1685/CSC06021] About DOI
