In this paper we describe an algorithm which is able to compensate an unknown defocus. This algorithm has been applied to recovering defocused en-face Optical Coherence Tomography images. Lateral resolution about 5 um has been achieved at distance from focal plane about 10 Rayleigh lengths.. Both numerical simulations and experiment have been performed to demonstrate the ability of the method.
