在本文中,我们考虑了逆粗糙表面problem.in近场光学成像。这一问题实际上是从多频近场数据中重建散射面及其阻抗系数,通过采用积分表示,可将其化为一个积分方案。我们用非线性积分方程方法求解了这个积分格式,并进一步发展了一种快速反演算法,可同时重建粗糙表面和阻抗系数。数值实验表明了算法的有效性。
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.
