In this work, an analytical technique is proposedfor the simultaneous determination of the interfaces positionsbetween two materials in a three-layer body. The estimate ismade from two noisy temperature measurements, one in themiddle of the body and the other on its right edge. A bound forthe estimation error is found, which depends on the noise in thetemperature measurements. Moreover, the local dependency ofthe estimated parameters on data is study by means of anelasticity analysis. Numerical examples with differentcharacteristics are used to show the performance of the proposedmethod.
