Born vs. Rytov: Is The Debate Over?
S. Leeman, Michael A. Fiddy, L. Zapalowski · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1985
The Born and Rytov approximations are re-examined, and several necessary conditions for their validity are derived without recourse to extensive numerical computations for simple objects of specific geometries. Some published statements as to the relative merits of the two approximations, as well as the identity of their validity domains, are suggested to be in error.
