Abstract
In this article we present a novel approach to quantitative imaging by Fourier domain optical coherence tomography. Using an eigenanalysis technique, a matrix model of the sample under test is fitted to real spectral data to extract layer dependent refractive index and thickness values. We demonstrate this method experimentally for a simple test artefact, made from silica test slides and highly scattering dental composite.
