A new method of making three-dimensional hologram by laser direct wrinting system was proposed, which was based on the principle of CGH and combined stereo holography. First, the experiment of fresnel computer generated hologram was conducted and the results demonstrated that it is feasible and rational to combine CGH with stereo holography. Then the three-dimensional model was sampled and the sampled image were processed by the principle of stereo holography and CGH. By digital holographic laser printing system, three-dimensional hologram was produced, which could be opticaly reproducted by laser, and the final results were analyzed and discussed.
