Abstract
This paper shows how the technique of acoustic diffraction tomography can be applied to the reconstruction both the magnitudes and directions of velocity vectors as well as to quantitative imaging of refraction inhomogeneities in quasisteady inhomogeneous flows and vortices. It has been stated that nonreciprocity of the sound scattering by flow offers additional information which can be used to carry out the separate reconstruction of velocity vector components, what was impossible in previous tomographic algorithms based on the inversion of time-of-flight data
