title: Space-shifting digital holography with dc term removal.
abstract: We describe a numerical space-shifting reconstruction approach in digital holography. This method is able to remove the dc term in the reconstruction very effectively by utilizing the periodicity and the space-shifting property of inverse discrete Fourier transform. Since the entire process does not need any additional holograms and specific requirements to recording optics, this approach can be a really convenient, practical, and widely effective way to remove the dc term from in-line or off-axis digital holography.
