Among the various methods to produce three-dimensional ( 3D ) images, holography occupies a special niche. Indeed, holograms provide highly realistic 3D images with a large viewing angle capability without the need for special eyewear. Such characteristics make We present a computer generated hologram (CGH) based setup for displaying 3D objects. An optically addressed spatial light modulator (OASLM) is used as a display device. By using the OASLM, the diffraction orders caused by the inter-pixel gap of an electrically We can often see the three-dimensional holographic communication technology in science fiction movies, using the principle of three-dimensional computer graphics, and the distant person or thing can been projected in the air in the form of three-dimensional.
