Inverse scattering solutions using low-coherence light.

We present a new wave-vector-space approach for solving inverse scattering problems. In our formulation, the theories for diffraction tomography and coherence gating are combined to explain 3D reconstruction with low-coherence light. Specifically, we apply this method to solve the scattering problem with broadband fields for transmission and reflection measurements. Our results can be applied to any interferometric measurements with low-coherence light, including optical coherence tomography, angle-resolved low-coherence interferometry, and white-light diffraction tomography.
