It is well established that synthetic aperture (SA) generation allows superresolved imaging. This is particularly important in digital holographic microscopy when ones want to retain either large object field of view or long working distance (or both) while maintaining a reasonable resolution limit. In this contribution, we show synthetic aperture superresolution (SASR) by interferometric imaging and analyze its capabilities considering object's edge processing. In a first proof-of-principle approach, we introduce the principles of edge enhancement by SASR. In a second method we provide two-dimensional (2-D) border analysis by SASR and comparison with other methods for edge processing. Finally, a third approach is presented regarding image edge processing of biological samples. [Figure not available: see fulltext.]
