摘要：
The technique of using computer-generated hologram (CGH) for 2-D and 3-D display based on virtual optics was researched widely. A new way, modified peak signal to noise ratio (PSNR) method was used to assess 3-D image quality reconstructed by CGH, and an iterative arithmetic was proposed to synthesize CGH perfectly. Furthermore, in the paper a novel way to encrypt 3-D information was proposed. Simulation experiments showed that CGH was an effective encryption technique, and Modified PSNR was a proper definite quantity analysis method for 3-D imaging. (C) 2009 Elsevier GmbH.
