This study proposes a dual-view integral imaging display that provides two three-dimensional scenes simultaneously. The optimal viewing distance can be easily adjusted by changing the horizontal pitch of the pinhole.
We propose a dual-view integral imaging display that provides two three-dimensional scenes at the same time. An adjustable pinhole array is generated by using a liquid crystal panel. The horizontal pitch of pinhole is adjustable, while the vertical one is unadjustable. The center of each elemental image is deviation from that of the corresponding pinhole. The light rays emitted from two kinds of elemental images are propagated into the left and right viewing directions. The horizontal viewing ranges are unrelated to the horizontal pitch of pinhole and the optimal viewing distance. By changing the horizontal pitch of pinhole, the optimal viewing distance is easily adjusted without loss of viewing angle. We developed an experimental apparatus and verified the proposed hypothesis. A dual-view integral imaging display that provides two three-dimensional scenes at the same time is proposed. The horizontal pitch of pinhole is adjustable, while the vertical one is unadjustable. By changing the horizontal pitch of pinhole, the optimal viewing distance is easily adjusted without loss of viewing angle.image
