Abstract

Recently, the VHOE(volume holographic optical element) is proposed as an optical directional modulator for the time-sequential multiview autostereoscopic 3D display system. In this paper, the exposure-time schedule of the photopolymer for implementing the optimized VHOE(volume holographic optical element) is analyzed. The recording property of the photopolymer is characterized by the function of the cumulative grating strength, which is a function of exposure energy. The cumulative grating strength dependence on the exposure energy are mathematically modeled by using the fourth-order polynomial function. Using this model, the exposure schedule of the photopolymer for recording the given multiple gratings has been calculated. This procedure is repeated until the exposure-time schedule is reached to the best condition. From some experimental results, a possible of implementing the optimized VHOE device by using the proposed exposure-time schedule is suggested.
