Based on the traditional basic theory for the making of the phase hologram, the digital phase hologram is studied in this paper. The experimental results demonstrated that, in the forming of digital phase type hologram, there exists a constituent parameter that corresponds to the exposure time of the traditional phase type recorded by holographic plate.By choosing the proper constituent parameter, the object wave field can also be reconstructed from the digital phase hologram. In this paper, the forming of the digital phase hologram and how to choose the constituent parameter are presented, finally, the comparison between the digital amplitude holography and digital phase holography in theory simulation under the same condition and the experiment verification are given out.
