Abstract

We explore the use of full-wave (Maxwell's Equations-based) forward and adjoint solvers to approach the inverse problem in Optical Coherence Tomography. We demonstrate that oscillatory artifacts in the electric susceptibility arise in the inversion process due to the intrinsic wave-nature of the forward and adjoint models. These methods however still perform well in reproducing measured data sets.
