Paper Abstract

In this paper we show the ability of well known in Synthetic Aperture Radar applications Phase Gradient Autofocus to recover defocused Optical Coherence Tomography images and achieve lateral resolution about 5 um at wide depth range. High-resolution details could be recovered from far-from-focal plane (defocused) regions. Both numerical simulations and experiment have been performed to demonstrate the ability of the method.
