目前最先进的用于增强现实（AR）应用的光学透明头戴式显示器缺乏相互遮挡能力，这是指在合并数字和物理对象时渲染正确的光阻挡关系的能力，从而使虚拟视图看起来像幽灵一样，缺乏逼真的外观。在本文中，我们使用现成的光学元件，提出了一种能够呈现逐像素相互遮挡的AR显示器的设计和原型。我们的原型利用一个微型有机发光显示器和一个液晶硅基空间光调制器来实现一个具有遮挡能力的AR显示器，提供30°对角线视场和1.24角分的角分辨率，在Nquist频率24.2周期/度下，整个视场的光学性能为>.4对比度。我们通过实验展示了在光线充足的环境中实现bbb100:1动态范围的单目原型。
State-of-the-art optical see-through head-mounted displays for augmented reality (AR) applications lack mutual occlusion capability, which refers to the ability to render correct light blocking relationship when merging digital and physical objects, such that the virtual views appear to be ghost-like and lack realistic appearance. In this paper, using off-the-shelf optical components, we present the design and prototype of an AR display which is capable of rendering per-pixel mutual occlusion. Our prototype utilizes a miniature organic light emitting display coupled with a liquid crystal on silicon type spatial light modulator to achieve an occlusion capable AR display offering a 30° diagonal field of view and an angular resolution of 1.24 arcminutes, with an optical performance of > 0.4 contrast over the full field at the Nquist frequency of 24.2 cycles/degree. We experimentally demonstrate a monocular prototype achieving >100:1 dynamic range in well-lighted environments.
