In this paper, we suggest the improved integration of a holographic display and a Maxwellian-view display using time-division multiplexing and describe an image rendering process for the proposed system. In general, the holographic displays have a resolution limit when used to represent a virtual 3D scene. In the proposed system, the holographic display processed relatively few layers of the virtual 3D scene, while the remaining objects were processed with a Maxwellian-view display to which was applied a Gaussian smoothing filter. Hence, we obtained the retaining holographic image quality, expanding the field of view, and reducing the computation time of the proposed system. The holographic display of the proposed system had an image size of 28 mm × 28 mm with a field of view of 1.02° and a 10.8 mm eye box. The Maxwellian-view display had an image size of 230 mm × 230 mm with a field of view of 22.6 ° and a 0.9 mm eye box diameter. Each display was integrated in time-division multiplexing of 40 Hz, and the proposed system was successfully verified.
在本文中，我们建议使用时分复用技术对全息显示器和麦克斯韦视图显示器进行改进集成，并描述了所提出系统的图像渲染过程。一般来说，全息显示器在用于呈现虚拟3D场景时存在分辨率限制。在所提出的系统中，全息显示器处理虚拟3D场景中相对较少的层，而其余对象则通过应用高斯平滑滤波器的麦克斯韦视图显示器进行处理。因此，我们在保持全息图像质量的同时，扩大了视野，并减少了所提出系统的计算时间。所提出系统的全息显示器图像尺寸为28 mm×28 mm，视野为1.02°，眼盒为10.8 mm。麦克斯韦视图显示器图像尺寸为230 mm×230 mm，视野为22.6°，眼盒直径为0.9 mm。每个显示器以40 Hz的时分复用方式集成，所提出的系统得到了成功验证。
