In this paper, we have investigated on the potentialities of digital holography
for whole reconstruction of wavefields. We show that this technique can be
efficiently used for obtaining quantitative information from the intensity and
the phase distributions of the reconstructed field at different locations along
the propagation direction. The basic concept and procedure of wavefield
reconstruction for digital in-line holography is discussed. Numerical
reconstructions of the wavefield from digitally recorded in-line hologram
patterns and from simulated test patterns are presented. The potential of the
method for analysing aberrated wave front has been exploited by applying the
reconstruction procedure to astigmatic hologram patterns.
