    Correction of defocused images in full-field optical coherence tomography using digital holography

    We propose the digital holographic technique that can mathematically reconstruct the distorted two dimensional en-face images obtained with full-field optical coherence tomography (FF-OCT). As a powerful biomedical imaging modality, FF-OCT provides inner microstructure images of a biological sample noninvasively but with a submicron depth resolution. The main advantage of the FF-OCT over other OCT techniques is that, it requires only depth scanning (C-scan) without any transverse mechanical scanning (B-scan). In a FF-OCT system based on a Michelson interferometer, not only the length of the reference arm should be matched with the length to the imaging plane in the sample arms ...
