One of advantages of parallel phase-shifting digital holography (PPSDH) compared with other digital holography techniques is the fast recording of three-dimensional (3D) objects. During the fast recording of a multiplexed hologram that contains at least three amounts of phase retardation, the optical energy of the hologram becomes smaller. Therefore, it is important to assess the minimum optical energy that can reconstruct the object with moderate reconstruction error. In this paper, we investigate experimentally the optical energy to reconstruct the object under weak light condition in PPSDH. We compare the numerical and experimental results. The experiment is in good agreement with numerical results when the sensitivity of the image sensor is taken into account.
