Time-Reversal Acoustics and Superresolution

First, introduction is followed by the theory of time reversal acoustics with the following coverage: time reversal acoustics and superresolution. The following applications of time reversal acoustics are given to medical ultrasound imaging and to ultrasonic nondestructive testing. The application to nondestructive testing has the following coverage: theory of time reversal acoustics for liquid–solid interface, experimental implementation of the time reversal mirror for nondestructive testing work, incoherent summation, time reversal of signals coming from a speckle noise zone and the iterative technique. Then, there is also the application of time reversal acoustics to landmine or buried object detection with the following coverage: introduction, theory, experimental procedure, experimental set-up, Wiener filter and experimental results. Next, there is the application of time reversal acoustics to nonlinear acoustics. The application of time reversal acoustics to nonlinear acoustics, nonlinear acoustic imaging, and the experimental set-up to analyse the nonlinear time reversal acoustics waves.
