Super-resolution in time-reversal acoustics.
The phenomenon of super-resolution in time-reversal acoustics is analyzed theoretically and with numerical simulations. A signal that is recorded and then retransmitted by an array of transducers, propagates back though the medium, and refocuses approximately on the source that emitted it. In a homogeneous medium, the refocusing resolution of the time-reversed signal is limited by diffraction. ...
متن کاملTime Reversal Super Resolution in Randomly Layered Media
In this paper we extend the range of applications of the previous work [Fouque et al, Wave Motion 42, 238-260 (2005)]. We consider first the case of an active source embedded below the surface in a finely layered random medium. We perform time reversal with a time reversal mirror placed at the surface and we consider here the case where this mirror is larger than the carrier wavelength. In cont...
متن کاملTime reversal through a solid-liquid interface and super-resolution
We present numerical computations that reproduce the time reversal experiments of Draeger, Cassereau and Fink (Draeger et al., 1998), where ultrasound elastic waves are time reversed back to their source with a Time Reversal Mirror (TRM) in a fluid adjacent to the solid. We also show numerically that multipathing caused by random inhomogeneities improves the focusing of the back-propagated elas...
متن کاملTime-reversal acoustics in biomedical engineering.
Time reversal is a very powerful method for focusing through complex and heterogeneous media and shows very promising results in biomedical applications. In this paper, we review some of the main applications investigated during the past decade. An iterative implementation of the time-reversal process allows tracking gallstones in real time during lithotripsy treatments. In this application dom...
متن کاملDemonstration of Super-Resolution and Super-Stacking Properties of Time Reversal Mirrors in Locating Seismic Sources
We demonstrate with synthetic seismic data the superresolution and super-stacking properties of time reversal mirrors (TRM). Tests on synthetic data show that TRM has the potential of exceeding the Rayleigh resolution limit by a factor of more than 9. This property is accompanied by the fact that TRM has a significant resilience to strong noise. Computer tests validate these properties by accur...
