Time Reversal, Focusing and Exact Inverse Scattering
- 594 Downloads
Focusing combined with time reversal is argued to be the physical basis of exact inverse scattering theory. These ideas yield the Newton—Marchenko equation, a foundational equation of inverse scattering theory, in a simple and physically convincing way. Since most applied imaging techniques are based on focusing and back-propagation, time reversal and focusing provide an important conceptual bridge between applied imaging and exact inverse scattering theory.

Newton, Inverse Schrödinger Scattering in Three Dimensions (Springer, Berlin, Heidelberg 1989) The term “miracle” was applied by Newton to the equation that extracts the potential from the reconstructed 3D wave field. The left-hand side of this equation (the potential) is a function of three variables, while the right-hand side is a function of five variables (time, direction of incidence and direction of scattering). For wave fields that correspond to actual potentials, the right-hand side is redundant in two of its dimensions. Newton referred to this fact as the “miracle”zbMATHGoogle Scholar
