摘要

投影型全息显示器是利用计算机全息术的三维（3D）显示器。这些显示器由一个投影透镜和一个离轴凹面镜相位分布的透明全息光学元件（HOE）组成，通过独立设计投影透镜的放大倍率和HOE屏幕的集光功能，使用户可以观察到较大的三维图像。然而，三维图像的观测区域是有限的。本文提出了一种利用多再现光的分时投影来扩大观测区域的方法。该方法实现了照明灯与全息图的同步，可将观测面积扩大1.7倍，同时保持图像尺寸是传统方法的两倍。此外，我们还成功地生成了每秒20帧的3D视频。

Projection-Type Holographic Display With Observation Area Expanded Using Time-Division Reproduced Light Generation System

Projection-type holographic displays are three-dimensional (3D) displays that utilize computer holography. These displays consist of a projection lens and a transparent holographic optical element (HOE) with off-axis concave mirror phase distribution and allow the user to observe a large 3D image by designing the magnification of the projection lens and the light-collecting function of the HOE screen independently. However, the observation area of the 3D image is limited. In this paper, we propose a method of expanding the observation area using time-division projection of multiple reproduced lights. With the proposed system developed to synchronize illumination lights and holograms, the proposed method can expand the observation area by a factor of 1.7 while maintaining the image size twofold that obtained by the conventional system. In addition, we succeeded in generating reproducing 3D video at 20 frames per second.

期刊介绍： IEEE Access® is a multidisciplinary, open access (OA), applications-oriented, all-electronic archival journal that continuously presents the results of original research or development across all of IEEE''s fields of interest. IEEE Access will publish articles that are of high interest to readers, original, technically correct, and clearly presented. Supported by author publication charges (APC), its hallmarks are a rapid peer review and publication process with open access to all readers. Unlike IEEE''s traditional Transactions or Journals, reviews are "binary", in that reviewers will either Accept or Reject an article in the form it is submitted in order to achieve rapid turnaround. Especially encouraged are submissions on: Multidisciplinary topics, or applications-oriented articles and negative results that do not fit within the scope of IEEE''s traditional journals. Practical articles discussing new experiments or measurement techniques, interesting solutions to engineering. Development of new or improved fabrication or manufacturing techniques. Reviews or survey articles of new or evolving fields oriented to assist others in understanding the new area.
