An efficient method is presented here for reconstructing dispersionless refractive profiles from scattering data. This procedure makes use of known reflection data to determine the refractive index of a semi-infinite slab. The numerical method presented here avoids matrix inversion, successive differentiation, and the solution of auxiliary algebraic or differential equations. Instead, the method relies on leapfrogging through space and time to solve a recently developed integral equation. Results for several new profiles are displayed, and evidence of the robustness of the technique with respect to noise is exhibited.
