Dictionary:Diffraction tomography

{{#category_index:D|diffraction tomography}} Tomography (q.v.) that relaxes the assumption that energy propagates as a ray, using wave-equation propagation for finding the physical properties under investigation. 1. A technique for crosshole tomography (q.v.) based on analysis of the scattered wavefield. 2. An inverse scattering technique that images diffracted and scattered data. See Devaney (1982).
