光学透明的增强现实（AR）系统是下一代计算平台，通过无缝结合物理和数字内容，可提供前所未有的用户体验。在过去的几年中，这些显示器的许多传统挑战都得到了显着改善，但是当今系统提供的AR体验远非无缝和感知现实。通常不支持物理对象和数字对象之间的相互一致的阻塞。当支持相互阻塞时，仅支持固定深度。我们提出了一种新的光学透明AR显示系统，该系统以深度依赖性，感知现实的方式使相互阻塞呈现。为此，我们基于焦点可调光学元件引入了Varifocal遮挡显示器，该光学元件包括一个Varifocal透镜系统和空间光调节剂，可实现深度校正后的硬边遮挡AR体验。我们得出了用于驱动此可调透镜系统的正式优化方法和封闭形式的解决方案，并演示了一个单眼型号闭塞功能的光学透明透明AR显示屏，能够在大深度范围内具有感知上现实的闭塞。
Optical see-through augmented reality (AR) systems are a next-generation computing platform that offer unprecedented user experiences by seamlessly combining physical and digital content. Many of the traditional challenges of these displays have been significantly improved over the last few years, but AR experiences offered by today's systems are far from seamless and perceptually realistic. Mutually consistent occlusions between physical and digital objects are typically not supported. When mutual occlusion is supported, it is only supported for a fixed depth. We propose a new optical see-through AR display system that renders mutual occlusion in a depth-dependent, perceptually realistic manner. To this end, we introduce varifocal occlusion displays based on focus-tunable optics, which comprise a varifocal lens system and spatial light modulators that enable depth-corrected hard-edge occlusions for AR experiences. We derive formal optimization methods and closed-form solutions for driving this tunable lens system and demonstrate a monocular varifocal occlusion-capable optical see-through AR display capable of perceptually realistic occlusion across a large depth range.
