“…Conventional multi-view 3D-display without glasses, such as parallax barrier, lenticular lens sheet type, has problem that the resolution is decreased according to the number of view and narrow viewing zone is built [1][2][3][4]. To overcome the above problems in this paper, we analyze and establish multiple recording methods of photopolymer for a full-resolution multiview auto-stereoscopic 3D display system incorporating VHOE (Volume Holographic Optical Element) and face-tracking.…”

In this paper, we propose multiple recording process of photopolymer for a full-color multi-view including multiple-view auto-stereoscopic 3D display system based on VHOE (Volume Holographic Optical Element). To overcome the problems such as low resolution, and limited viewing zone of conventional 3D-display without glasses, we designed multiple recording condition of VHOE for multi-view display. It is verified that VHOE may be optically made by angle-multiplexed recording of pre-designed multiple-viewing zone that uniformly is recorded through optimized exposure-time scheduling scheme. Here, VHOE-based backlight system for 4-view stereoscopic display is implemented, in which the output beams that playing a role reference beam from LGP(Light guide plate)t may be sequentially synchronized with the respective stereo images displayed on the LCD panel.

The capability of polyvinyl alcohol-acrylamide photopolymer materials to obtain angularly multiplexed holographic gratings has been demonstrated [Appl. Phys. B 76, 851 (2003)]. A combination of two multiplexing methods-peristrophic and angular multiplexing-is used to record 60 holograms. An exposure schedule method is used to optimize the capability of the photopolymerizable holographic material and obtain holograms with a higher, more uniform diffraction efficiency. In addition, because of this exposure schedule method, the entire dynamic range (M#) of the material will be exploited, obtaining values of approximately M# ϳ 9 in layers approximately 800 m thick.

Two different types of multiplexing are used to store 90 holograms at the same location in a polyvinyl alcoholacrylamide photopolymer material. In the first, the 90 holograms are stored using only peristrophic multiplexing, whereas in the second a combination of angular and peristrophic multiplexing is used. The results (diffraction efficiency and dynamic range, M#) obtained with these two multiplexing techniques are compared. With the first, the dynamic range was M# ϭ 13 and with the second M# ϭ 8. An exposure schedule method is used to calculate the exposure time necessary to store the holograms with a more uniform, higher diffraction efficiency.
