摘要

针对集成成像裸眼三维显示技术受三维再现像再现深度的限制而无法实现大规模应用的问题

提出了一种基于小发散角的投影式集成成像三维再现深度的拓展方法。该方法利用投影式集成成像显示系统和一个辅助透镜来控制元素图像阵列中各像素点的发散角度

利用小发散角度实现了再现深度的拓展。与传统的多中心平面拓展技术相比

该方法具有系统结果简单

扩展效率高

对显示器件要求较低的优点。光学实验结果显示

当元素图像阵列中各像素点的发散角为1.79°时

集成成像三维再现深度是原来的6.4倍

比传统的多中心平面扩展技术实现的4倍再现深度提升了60%

为提高集成成像三维再现像的品质提供了一种有效的解决方法。

Abstract

As the integral imaging three-dimensional(3D) display technology is limited by the depth of field in a reconstructed image

it can not be widely used in the fields of 3D display. Therefore

this paper proposes a method to enhance the depth of field in a projection-type integral imaging system based on the angle control. To enhance the depth of field

an additional lens is used to control the diverging angle of every pixel in the elemental image array. Contrast to the conventional method with multi-layers

the proposed method has advantages in simpler systems

higher efficiency and lower requests for display devices. Experimental results show that the depth of field is 6.4 times that of original one when the diverging angle is 1.79?. And as compared to the conventional method with an enhancement of 4 times depth of field

the proposed method has increased by 60% in efficiency. These results demonstrate that the proposed method gives a new way to enhance the image quality for integral imaging display systems.
