基于掩膜板阵列的消串扰集成成像3D显示方法

Crosstalk-free integral imaging 3D display method based on a mask array

随着立体显示技术的不断发展,集成成像三维(three-dimensional,3D)显示技术受到广泛的认可,但普遍存在的视觉串扰现象严重影响其立体观看效果。为了减小集成成像中相邻图像元间的串扰光线,提高观看舒适度,本文提出了一种基于掩膜板阵列的消串扰集成成像3D显示方法。该方法通过特定参数设计的掩膜板阵列,能有效阻挡相邻图像元间的光线,从而消除视区串扰现象,且结构简单,易于制备。文中分析了集成成像3D显示视区分布关系,以及无串扰立体视区范围和立体观看视角大小,详细阐述了基于掩膜板阵列的消串扰集成成像3D显示方法的设计原理和结构,并通过实验验证了该显示方法能有效阻挡相邻图像元间的视区串扰。随着观看视角逐渐增大,串扰图像逐渐被阻挡直至全部消失,有效提升了集成成像3D显示的观看体验。

With the rapid development of stereoscopic display technology,integral imaging three-dimen⁃sional(3D)display technology has been widely researched.But the visual crosstalk in integral imaging se⁃riously affects its stereoscopic visual effect.In order to reduce the crosstalk and improve the visual com⁃fort,a crosstalk-free integral imaging 3D display based on a mask array was proposed.The mask array was particularly designed to block the light from the adjacent elemental images.The proposed structure can effectively eliminate the crosstalk caused by the adjacent elemental images,and it is compact and easy to be fabricated.In this paper,the distribution of viewing area and the viewing angle of integral imaging were analyzed,and the design principle and structure of the proposal were described in detail.The experi⁃mental results show that the proposed structure can completely block the crosstalk caused by the adjacent elemental images and effectively reduce the crosstalk in integral imaging.As the viewing angle increasing,the crosstalk image was gradually blocked and eventually disappeared,the 3D visual effect was improved.
