Description
Summary:The imaging resolution in optical coherence tomography can be improved by using deconvolution techniques. Both the Time-Domain OCT (TD-OCT) and the Fourier-Domain OCT (FD-OCT) are considered. A deconvolution technique based on Wiener filtering and autoregressive spectral extrapolation (ASE) allows a resolution enhancement by a factor of 4 in TD-OCT and of 2 in FD-OCT. The performance of both approaches is evaluated from TD and FD-OCT measurements of the thickness of the upper epoxy layer of a carbon-epoxy composite.
