  • Title: Subaperture correlation based digital adaptive optics for full field optical coherence tomography.
    Author: Kumar A, Drexler W, Leitgeb RA.
    Journal: Opt Express; 2013 May 06; 21(9):10850-66. PubMed ID: 23669942.
    Abstract:
    This paper proposes a sub-aperture correlation based numerical phase correction method for interferometric full field imaging systems provided the complex object field information can be extracted. This method corrects for the wavefront aberration at the pupil/ Fourier transform plane without the need of any adaptive optics, spatial light modulators (SLM) and additional cameras. We show that this method does not require the knowledge of any system parameters. In the simulation study, we consider a full field swept source OCT (FF SSOCT) system to show the working principle of the algorithm. Experimental results are presented for a technical and biological sample to demonstrate the proof of the principle.
