We present a retinal-projection-based near-eye display with switchable multiple viewpoints by polarization-multiplexing. Active switching of viewpoints is provided by the polarization grating, multiplexed holographic optical elements and polarization-dependent eyepiece lens that can generate one of the dual-divided focus groups according to the pupil position. The lightguide-combined optical devices have a potential to enable a wide field of view (FOV) and short eye relief with compact form factor. Our proposed system can support a pupil movement with an extended eyebox and mitigate image problem caused by duplicated viewpoints. We discuss the optical design for guiding system and demonstrate that proof-of-concept system provides all-in-focus images with 37 degrees FOV and 16 mm eyebox in horizontal direction.

具有可切换视点的视网膜投影型基于光导的近眼显示器。

我们提出了一种基于视网膜投影的近视显示器，通过偏振复用可切换多个视点。偏振光栅，多路复用全息光学元件和偏振相关的目镜可提供视点的主动切换，这些偏振可根据瞳孔位置生成双焦点组之一。与光导结合的光学设备具有实现紧凑型外形的宽视场（FOV）和短视缓解的潜力。我们提出的系统可以支持带有扩展眼罩的瞳孔移动，并减轻由重复视点引起的图像问题。我们讨论了导向系统的光学设计，并演示了概念验证系统可提供全焦点图像，其水平方向的FOV为37度，眼框为16 mm。
