Abstract

We report results on the problem of OCT spatial resolution degradation with depth due to tissue scattering of super- broadband probing light. Analytical and numerical theoretical models of the OCT signal are discussed. Experiments were also carried out with turbid phantoms. Results suggest that OCT spatial resolution degrades rather fast and comes to an asymptotic form at the depth of few photon scattering lengths independently of the initial coherence duration of the OCT source of light. In certain cases it imposes a burden for the application of super broadband sources of the probing light.
