In phase-shifting digital holography, a hologram is usually recorded on a CCD sensor instead of a photographic plate. The complex amplitude of the object is analyzed from the phase-shifted holograms obtained by shifting the phase of the reference beam. The reconstructed image can be calculated from the complex amplitudes of the hologram [1].
