Time reversal method for thermoacoustic acoustic tomography in elastic media: convergence with sharp observation time
arXiv:1707.05822
Abstract
In this article, we consider the inverse source problem arising in photoacoustic tomography in elastic media. We show that the time reversal method, proposed by Tittelfitz [Inverse Problems 28.5 (2012): 055004], converges with the sharp observation time without any constraint on the speeds of the longitudinal and shear waves.
