Abstract
The occlusion function benefits augmented reality (AR) in many aspects. However, existing occlusion-capable optical see-through augmented reality (OC-OST-AR) displays are designed by integrating virtual displays into a dedicated occlusion-capable architecture, hereby, we miss merits from emerging OST-AR displays. In this article, we propose an external occlusion module that can be added to common OST-AR displays. Per-pixel occlusion is supported with a small form-factor by using polarization-based optical path compression. The occlusion function can be switched on/off by controlling the incident light polarization. A prototype within a volume of 6×6×3cm is built. A preliminary experiment proves that occlusion is realized successfully.
