Single-shot off-axis hologram reconstruction by using fractional Fourier transform domain filtering based on spatial-domain extending and hologram partitioning

A method of single-shot off-axis digital hologram reconstruction by extending and partitioning the hologram in its spatial domain, filtering in its fractional Fourier transform domain, and merging in the reconstruction imaging domain is presented, which can enhance the resolution of the reconstru…
