360 Degree Crosstalk-Free Viewable 3D Display Based on Multiplexed Light Field: Theory and Experiments

A 360° three-dimensional (3D) display is one of the most attractive displays for full parallax in horizontal direction. In this paper, we proposed two 360° crosstalk-free 3D autostereoscopic display methods based on pyramidal mirrors-based 3D light field multiplexing and diaphragms. Display performances of proposed displays were analyzed. We fabricated two 360° display prototypes based on the n-gonal pyramidal mirrors assemblage and flat 3D displays. Moreover, we evaluated our proposed methods by simulations and experiments. Experimental results as well as simulation results were consistent with theoretical analysis based on the geometric optics. Furthermore, the proposed schemes and theories may provide a guideline for light field multiplexing and wide viewing angle augmented reality.
