摘要
随着元宇宙概念的逐渐火爆,用于虚拟现实和增强现实(VR/AR)的可穿戴近眼显示设备也获得了巨大的关注。一款终极的VR/AR头戴式设备必须将显示器、传感器和处理器集成在一个紧凑的外壳中,人们可以长时间舒适地佩戴,同时提供良好的沉浸式体验和友好的人机交互体验。面向视觉舒适度的设计理念对于下一代VR/AR设备至关重要。在众多可以提供三维视觉效果的显示技术中,全息显示技术能够提供包含所有三维观看线索的真实自然的三维显示效果,同时由于其衍射成像的特点在人眼视觉像差矫正及保持紧凑外形尺寸等方面都具有独特的优势,成为了未来近眼显示设备的潜在理想技术方案。在这篇综述中,从视觉舒适度的角度调研和总结了全息近眼显示技术的最新进展。首先在视觉感知的背景下介绍了人眼视觉系统,随后对全息近眼显示在动眼眶、视场角、散斑噪声、三维波前计算和全彩色显示等有关视觉舒适度的研究方向进行了全面综述,最后总结和讨论了全息近眼显示技术在未来的潜在应用场景。
With the concept of metaverse gradually becoming popular,wearable near-eye display devices for virtual and augmented reality(VR/AR)have received considerable attention.An ideal VR/AR headset device must integrate the display,sensor,and processor into a compact form factor,so that people can wear it comfortably for long durations,while providing a good immersive experience and friendly human-computer interaction experience.The design concept of visual comfort is crucial for the next generation VR/AR equipment.Among many display technologies that can provide threedimensional visual effects,holographic display technology can provide real and natural three-dimensional display effects including all three-dimensional viewing clues.Meanwhile,owing to its diffraction imaging characteristics,holographic display technology has unique advantages in human visual aberration correction and maintaining compact overall dimensions,and it has become a potential ideal technical solution for near-eye display equipment.In this review,the latest developments in the holographic near-eye display technology was investigated and summarized from the perspective of visual comfort.First,the human visual system was introduced in the context of visual perception.Then,the research works of holographic near-eye display in eyebox,field of view,speckle noise,hologram generation algorithms,and fullcolor display were comprehensively reviewed.Finally,the potential application scenarios of holographic near-eye display technology were summarized and discussed in this study.
