Abstract
In digital holography technique, we use CCD for recording. The reconstruction executes in computer and can also realize special reconstruction like conventional holography. The computer-reconstruction can be carried out by mathematical transform for single-fringe hologram, which has larger additive error. Now we import phase-shifting technique which can improve the reconstructive precision. Meanwhile it brings new problems because this means can only receive the object information on holography plane. In this paper, we present virtual interferometry method and reverse transform method to solve reconstruction problems in phase-shifting technique and verify the methods by simulation.
