我们提出了一种用于3D显示器的光学系统设计，它是球面的、全视差的、能够遮挡的、具有宽观看区域和无头部跟踪的。所提出的系统为3D显示提供了一种新的方法，从而解决了传统光场显示结构的局限性。具体地说，球面全视差光场显示器很难实现，因为弯曲光场显示器的传统结构是具有挑战性的。该系统的关键部件是一个特别设计的球镜和一个高速投影仪。球镜单轴旋转并将来自投影仪的光线反射到不同的角度。这些光线的强度由投影仪控制。球镜内部虚拟物体的光线被重建，系统基于时分复用方法作为光场显示器。我们通过3D打印和金属电镀实现了这面球镜。样机成功显示了一幅3D图像，验证了系统的可行性。因此，我们的系统适合同时向多个观众显示3D图像，并且可以有效地应用于艺术或广告装置中。
We present an optical system design for a 3D display that is spherical, full-parallax, and occlusion-capable with a wide viewing zone and no head tracking. The proposed system provides a new approach for the 3D display and thereby addresses limitations of the conventional light-field display structure. Specifically, a spherical full-parallax light-field display is difficult to achieve because it is challenging to curve the conventional structure of the light-field displays. The key elements of the system are a specially designed ball mirror and a high-speed projector. The ball mirror uniaxially rotates and reflects rays from the projector to various angles. The intensities of these rays are controlled by the projector. Rays from a virtual object inside the ball mirror are reconstructed, and the system acts as a light-field display based on the time-division multiplexing method. We implemented this ball mirror by 3D printing and metal plating. The prototype successfully displays a 3D image and the system feasibility is confirmed. Our system is thus suitable for displaying 3D images to many viewers simultaneously and it can be effectively employed as in art or advertisement installation.
