视网膜投影AR近眼显示研究进展

Research progress on retinal projection AR near-eye displays

增强现实(Augmented Reality,AR)近眼显示技术可将虚拟与现实世界的信息叠加在一起,为用户眼前营造出虚实结合的场景,成为连接现实和虚拟世界的桥梁。视网膜投影(Retinal Projection Displays,RPD)显示,又称为麦克斯韦近眼显示(Maxwellian Displays),可有效化解调焦-辐辏冲突,提供无眩晕的近眼显示观感,在AR近眼显示领域受到广泛关注。近年来,研究人员围绕扩展出瞳(Eyebox)、全彩显示等重要问题提出了不同的解决方案。本文主要介绍麦克斯韦增强AR近眼显示的工作原理,综述其核心器件及发展进程,并展望未来的发展前景与趋势。

Augmented reality(AR)near-eye display technology combines the virtual information and real worlds,creating a scene of virtual and real integration for users,becoming a bridge connecting reality and the virtual world.Retinal projection display(RPD),also known as Maxwellian displays,has received widespread attention in the field of AR near-eye display due to its ability to effectively resolve vergenceaccommodation conflict and provide a near-eye display without dizziness.With the progress of research,Maxwellian near-eye display has multiple implementation methods,and different display methods have proposed different solutions around the main problems of expanding eye movement range and full-color display.This article mainly introduces the working principle of Maxwellian near-eye displays,summarizes the core devices used for Maxwellian near-eye displays and their development progress,and looks forward to the future development prospects and trends of Maxwellian near-eye displays.
