Multiview 3D Display System based-on Volume Holographic Lenticular Element

摘要

In this paper, a new VHLE(volume holographic lenticular element)-based multiview autostereoscopic 3D display system is proposed and implemented. In the proposed system, the lenticular sheet which has been used in the conventional autostereoscopic 3D display system is optically implemented by using the multiplexed volume hologram, which is called a VHLE. Thus, like the conventional lenticular sheet, the VHLE can be used as an optical directional modulator in the multiview stereoscophic display system. This VHLE can be made by using the volume holographic technique in which both of angular multiplexing and space-division multiplexing are used to record the diffraction gratings in the holographic recording materials. Once the diffraction gratings are recorded in the volume hologram, then this holographic device can play the same role of the conventional lenticular sheet. In addition, a design tool for synthesizing the VHLE for the implementation of an arbitrary multiview 3D display system is also discussed. Through some experimental results, a possibility of implementing the VHLE-based multiview autostereoscopic display system is presented
