Paper Abstract

Digital holography has a limited possibility to reconstruct object details because of an insufficient pixel number of commercially available CCD cameras. Software hologram apodization introduces an additional damping of registered object information and, in general, it can be considered as a disadvantageous process. However, for the reconstruction of phase objects in digital holography the unwrapping procedures are indispensable. Moreover, for surfaces with considerable roughness depth there are large phase changes between neighbor CCD camera pixels. Therefore unwrapping procedures can introduce essential errors to reconstructed phase images. In the paper, besides general considerations on the apodization in digital holography, experimental and computer simulation results of the hologram apodization for surface shape measurements are presented.
