In numerous applications, Fourier-domain optical coherence tomography(FD-OCT) suffers from a limited imaging depth due to signal roll-off, a limitedfocal range, and autocorrelation noise. Here, we propose a parallel full-fieldFD-OCT imaging method that uses a swept laser source and an area camera incombination with an off-axis reference, which is incident on the camera at asmall angle. As in digital off-axis holography, this angle separatesautocorrelation signals and the complex conjugated mirror image from the actualsignal in Fourier space. We demonstrate that by reconstructing the signal termonly, this approach enables full-range imaging, i.e., it increases the imagingdepth by a factor of two, and removes autocorrelation artifacts. The previouslydemonstrated techniques of inverse scattering and holoscopy can thennumerically extend the focal range without loss of lateral resolution orimaging sensitivity. The resulting, significantly enhanced measurement depth isdemonstrated by imaging a porcine eye over its entire depth, including cornea,lens, and retina. Finally, the feasibility of in vivo measurements isdemonstrated by imaging the living human retina.
