Description

Quantitative NDE is, by its very nature, a discipline within which inverse source and scattering problems abound. Determining the shape of a scattering obstacle from the obstacle’s scattering amplitude or the index of refraction distribution of an inhomogeneous object from scattered field measurements performed in one or more scattering experiments are examples of inverse scattering problems encountered in quantitative NDE. Determining the value of a wavefield (e.g., the pressure of a sound wave) over some surface from measurements of the wave at points removed from the surface is a special case of an inverse source problem. Pulse echo and transmission tomography, holographic imaging and emission tomography are further examples where the inverse source or scattering problems arise.
