A phase-only hologram generation method of three-dimensional (3D) objects is proposed. The information of the 3D object is recorded into a series of defocused images which are obtained under regular incoherent illumination. The phase-only hologram is generated from these images with iterative method. The propagation is simulated based on Rayleigh-Sommerfeld diffraction and experiment results verified the principle.
