Abstract
In this study, we propose a method to enhance the spatial resolution of digital holographic microscopy with speckle illuminations. In this method, speckle patterns are generated from coherence light passing through ringslit apertures instead of the most typical circular apertures, to obtain higher numerical aperture. The results show that a reconstructed image with the higher resolution is obtained using ring-slit apertures.
