Fluid flow imaging by means of wide-band diffraction tomography.
The problem of reconstructing a two-dimensional distribution of fluid flow from wide-band scattering measurements is considered. Reciprocal scattering measurements are employed, meaning that scattered waves are recorded between a source and receiver, and again with the source and receiver interchanged. As shown, such measurements allow the reconstruction of a fluid flow image separate from that of a distribution of stationary acoustic velocity inhomogeneities.
