Paper Abstract

Stochastic models of multilayer tissue and low-coherence interferometric signals are considered. The extended Kalman filtering method is investigated applied to dynamic evaluating layer borders of multilayer tissues in Optical Coherence Tomography (OCT). Increased resolution of layer borders is provided by direct transforming input fringe signal samples series to dynamic estimates of fringe amplitude and local envelope maximum positions. Results of experimental estimates of the method resolving power in the case of partially overlapped envelope peaks presented and discussed.
