"Time reversal acoustics (TRA) is a promising tool that is used for non-destructive testing of materials. Its great advance is in sensitivity for third order nonlinear behavior that is crucial in assessment of material quality. Evaluation of third order nonlinearity coefficient can be done by ESAM (Excitation Symmetry Analysis Method). This method is generalization of well-known pulse inversion technique. I will discuss disadvantages of ESAM and then I will describe techniques that could be used for enhancement of this method. And at the end of my speech, I would like to talk about possible ways of visualisation of results obtained by TRA."@en . "Data processing for results of time reversal acoustics"@en . . "S" . .
