Ground autostereoscopic display with new type non-uniform barrier

This paper analyzes the drawbacks of traditional parallax barrier with the uniform slits for large-scale ground autostereoscopic display firstly. And then an approach of designing non-uniform barrier for ground display is proposed by use of the reverse ray-tracing technique and Iterative approximate algorithm. Form the numerical simulation, it is proved that low cross-talk feature of the non-uniform barrier is an advantage relative to traditional parallax barrier.
