摘要：
We propose a crosstalk-free integral imaging three-dimensional (3D) display using a pinhole array. It consists of a back light unit, a pinhole array and a liquid crystal panel. The pinhole array, which is attached to the back light unit, is located between the back light unit and the liquid crystal panel. Three imaging models of the integral imaging 3D display with different pinhole arrays are analyzed to reveal the relationship between the aperture width of the pinhole array and the crosstalk. The optimal value of the aperture width of the pinhole array is also obtained to eliminate the crosstalk. A prototype using the optimal pinhole array is developed, and the experiment results agree well with the theory.
