摘要
随着增强现实(AR)头戴显示器的迅速发展,自由曲面光学系统已成为其光学设计的主要方案之一。本文首先分析了透射式头戴显示器光学系统面临的主要问题与挑战,重点讨论了视场角、出瞳直径、角分辨率和系统体积等参数之间的协调关系,以及辐辏调节和屈光度调节所带来的挑战,并提出了解决方案,平衡各项参数,实现更佳的用户体验。接着,文章总结了自由曲面透射式头戴显示器的几种结构类型及近年来的研究进展,深入分析了不同方案的优缺点。最后,展望了该领域实现虚拟现实互动以及解决辐辏调节冲突的发展趋势,并指出多焦面显示、手势识别、自适应光学等技术的潜力,这些创新将推动自由曲面透射式头戴显示器在增强现实与虚拟现实领域的进一步应用。皆在为设计更高效、轻便、用户友好的头戴显示光学系统提供了理论基础和研究方向。
As augmented reality(AR)head-mounted displays rapidly advance,freeform optical systems have become one of the main solutions in optical design.This paper first analyzes the key issues and challenges faced by optical see-through head-mounted display systems,focusing on the balance between parameters such as field of view,exit pupil diameter,angular resolution,and system size,as well as the challenges posed by vergence-accommodation conflict.Solutions are proposed to optimize these parameters and enhance the user experience.The article then summarizes several structural types of freeform optical see-through head-mounted displays and recent research developments,providing an in-depth analysis of the advantages and disadvantages of various approaches.Finally,it explores trends in the field,particularly in achieving virtual reality interaction and addressing the vergence-accommodation conflict.The paper highlights the potential of technologies such as multi-focal displays,gesture recognition,and adaptive optics,noting that these innovations will further drive the application of freeform optical see-through head-mounted displays in both augmented and virtual reality.This work lays the theoretical foundation and research direction for designing more efficient,lightweight,and user-friendly head-mounted display optical systems.
