One-dimensional dual-view integral imaging 3D display based on polarizer parallax barrier

为了解决视区分离的问题,设计了一种基于偏振光栅的一维集成成像双视3D显示器,建立了3D成像模型,详细阐述了一维集成成像双视3D显示的原理;通过几何光学推导视区宽度以及观看视角的计算公式;研制了基于偏振光栅的一维集成成像双视3D显示测试装置,在左18°到右18°的范围内,通过左偏振眼镜和右偏振眼镜在同一视区内分别观看到两个不同的3D图像。

To resolve separated viewing zones, a one-dimensional dual-view integral imaging threedimensional(3D) display based on a polarizer parallax barrier was proposed. The imaging model of the one-dimensional dual-view integral imaging 3D display based on the polarizer parallax barrier was established. The principle of the one-dimensional dual-view integral imaging 3D display was illustrated in detail. The calculation formulas of the width of the viewing zone and the viewing angle were deduced by using geometrical optics. A test equipment of the one-dimensional dual-view integral imaging 3D display was developed. By using left and right polarizer parallax barriers, two different 3D images were viewed from 18° to the left and the right in the same viewing zone.
