在这项工作中，我们的目标是实现一个宽视角和节省空间的配置，在投影型一体化的3D显示器组成的投影仪和透镜阵列。在传统方法中，对于宽视角，光线应该以大入射角入射在透镜阵列上。为了实现大的入射角，投影仪被对角地安装在透镜阵列后面。这需要在显示器后面为投影仪提供大的空间。我们提出了一种投影方法，实现了宽视角使用节省空间的配置，其中一个投影仪安装在透镜阵列后面。在所提出的配置中，在投影仪和透镜阵列之间彼此面对地布置两个反射镜。光线从投影仪的镜像位置通过这两个反射镜之间的多次反射进入透镜阵列。所提出的方法除了直接安装在透镜阵列后面的投影仪之外不需要投影仪。以这种方式，通过缩小尺寸的系统实现宽视角。首先，对所提出的配置进行仿真并评估其可行性。其次，基于仿真结果，在实验中所提出的配置的规格进行了评估。然后准备实际的显示系统用于实验。作为模拟和实验的结果，使用采用一个投影仪的配置来实现需要采用三个或更多个投影仪的配置的视角。
In this work, we aim to realize a wide viewing-angle and a space saving configuration in a projection-type integral 3D display composed of a projector and lens array. In the conventional method, for a wide viewing-angle, light rays should be incident on the lens array at a large incident angle. In order to achieve a large incident angle, projectors are installed diagonally behind the lens array. This requires a large space for projectors behind the display. We propose a projection method that realizes a wide viewing-angle using a space saving configuration in which one projector is installed behind the lens array. In the proposed configuration, two mirrors are arranged facing each other between the projector and the lens array. Light rays enter the lens array from the mirror image positions of the projector through multiple reflections between these two mirrors. The proposed method requires no projector other than the projector installed directly behind the lens array. In this way, wide viewing angle is achieved with a downsized system. First, the proposed configuration was simulated and its feasibility was evaluated. Second, based on the simulation results, the specifications of the proposed configuration were evaluated in the experiment. The actual display system was then prepared for the experiment. As a result of the simulation and experiment, a viewing-angle that requires a configuration employing three or more projectors was realized using a configuration employing one projector.
