In this paper, we consider an inverse rough surface scattering problem.in near-field optical imaging. This problem is actually to reconstruct.the scattering surface as well as its impedance coefficient from.multifrequency near-field data, and can be reduced into an integral.scheme by employing an integral representation. We solve this.integral scheme by a non-linear integral equation method, and further.develop a fast inversion algorithm for reconstructing both the rough.surface and the impedance coefficient. Numerical experiments are.presented to illustrate the effectiveness of the algorithm.
