Paper Abstract

In digital holography the imaging process consists of physical registration using CCD camera and digital image reconstruction with specialized software. Amplitude gradients of the reconstruction field at the hologram plane influence significantly the phase reconstruction quality. The field truncation by hologram edges is of particular concern. The image reconstruction process can be software repeated several times using various apodization functions. Basing on phase imaging changes introduced by different apodization functions a decrease of phase errors can be achieved for some object types. Basing on the results received from experimental measurements and computer simulations for some object examples the advantages and disadvantages of the proposed method will be presented.
