Paper Abstract

An object structure can be better resolved in optical coherence tomography by using inverse scattering theory, which takes into account the finite beam width and focusing. Specifically, we show experiments where scatterers are resolved outside of the confocal region such that resolution is uniform to the focused region. Numerical simulations demonstrate the effectiveness of this technique. When the algorithm is applied to experimentally-acquired OCT data, the transverse resolution outside of the confocal parameter is improved, extending the apparent confocal parameter range. The experimental results validate improvement for capabilities of OCT to perform high-resolution cross-sectional imaging.
