Paper Abstract

Resolution in digital holography microscopy can be improved by enlarging the hologram aperture. We review different techniques for resolution enhancement in digital holography, and present a system for reconstructing single-exposure online (SEOL) digital holograms with improved resolution using a synthetic aperture. In our method, several recordings are made in order to compose a synthetic aperture, shifting the camera within the hologram plane. After processing the synthetic hologram, an inverse Fresnel transformation provides an enhanced resolution reconstruction. The method employs a simple set-up, including no microscope objective.
