Abstract

A theory with supporting experimental evidence is presented for reconstructing the three-dimensional fluid velocity vector field and temperature field in a moving medium from a set of measurements of the acoustic propagation time between a multiplicity of transmitter and receiver locations on a stationary boundary surface. The inversion of the integrals relating the acoustic propagation path to the propagation time measurements is affected by linearization and discrete approximation of the integrals and application of an algebraic reconstruction technique (ART). Since this technique does not require the presence of scattering centers or the optical transparency of the medium, it may be applied in many cases (i. e. , turbid, opaque, or chemically pure media) where Doppler or optical (e. g. , laser holography) methods fail.
