    Abstract

    This study presents a superresolution imaging technique based on synthetic aperture digital holographic microscopy (SA-DHM). The synthetic aperture for superresolution imaging in digital holographic microscopy is theoretically derived and analyzed, which indicates that the frequency coverage and spatial resolution increase as the effective aperture size. We experimentally performed the scanning synthetic aperture for superresolution and tomographic imaging in the DHM system. The experimental results show that the spatial resolution of the DHM system can increase up to two times than that in using conventional numerical-aperture microscopy.
