A generalized diffraction tomography algorithm

摘要: Available diffraction tomography algorithms are based on Fourier transform techniques and require either plane‐wave illumination in a uniform background medium or far‐field combined with paraxial approximations. In this paper generalized algorithm is introduced that can handle both irregularly spaced measurement data, nonuniform models, general aquisition geometries. Using data from water tank experiments, the method’s ability to yield high‐quality reconstructions of geometry velocity, as long weak‐scattering assumption satisfied, demonstrated.
