Inverse-scattering theory within the Rytov approximation

Opt Lett. 1981 Aug 1;6(8):374-6. doi: 10.1364/ol.6.000374.


A method for determining the internal structure of a localized scattering potential from field measurements performed outside the scattering volume is developed by using the Rytov approximation. The theory is compared with the inverse-scattering method within the Born and eikonal approximations and found to reduce to these methods in the weak-scattering (Born) and very-short-wavelength (eikonal) limits.
