我们提出了一种能够相互遮挡的光学透明头戴式显示器。相互遮挡是增强现实显示的一个属性，真实物体可以遮挡虚拟物体，虚拟物体也可以遮挡真实物体。对于用户来说，为了实现叠加在真实环境上的真实图像和虚拟图像之间的无差异感知，相互遮挡是某些应用中强烈需要的属性。本文从移动性（即紧凑性）、分辨率和基于切换速度的标准提出了显示硬件的突破。具体来说，我们专注于与虚拟物体能够遮挡真实物体相关的研究。该系统的核心是一个空间光调制器（SLM）和基于偏振的光学系统，它允许我们阻挡或通过通过头戴式显示器观看的场景的某些部分。物镜将场景成像到SLM上，调制后的图像通过目镜映射回原始场景。我们正在将计算机生成的图像与场景的调制版本结合起来，形成用户将看到的最终图像。
We are proposing an optical see-through head-worn display that is capable of mutual occlusions. Mutual occlusion is an attribute of an augmented reality display where real objects can occlude virtual objects and virtual objects can occlude real objects. For a user to achieve the perception of indifference between the real and the virtual images superimposed on the real environment, mutual occlusion is a strongly desired attribute for certain applications. This paper presents a breakthrough in display hardware from a mobility (i.e. compactness), resolution, and a switching speed based criteria. Specifically, we focus on the research that is related to virtual objects being able to occlude real objects. The core of the system is a spatial light modulator (SLM) and polarization-based optics which allow us to block or pass certain parts of a scene which is viewed through the head-worn display. An objective lens images the scene onto the SLM and the modulated image is mapped back to the original scene via an eyepiece. We are combining computer generated imagery with the modulated version of the scene to form the final image a user would see.
