Occlusion of a real scene by displayed virtual images mitigates incorrect depth cues and enhances image visibility in augmented reality applications. In this Letter, we propose a novel optical scheme for the occlusion-capable optical-see-through near-eye display. The proposed scheme uses only a single spatial light modulator, as the real-scene mask and virtual image display simultaneously. A polarization-based double-pass configuration is also combined, enabling a compact implementation. The proposed scheme is verified by optical experiments which demonstrate a 60 Hz red-green-blue video display with a 4-bit depth for each color channel and per-pixel dynamic occlusion of a 90.6% maximum occlusion ratio.

使用单个数字微镜设备的可遮挡的光学透明近眼显示器。

显示的虚拟图像对真实场景的遮盖可减轻错误的深度提示，并增强增强现实应用程序中的图像可见性。在这封信中，我们提出了一种具有遮挡功能的光学透明近眼显示器的新型光学方案。所提出的方案仅使用单个空间光调制器，同时作为实景掩模和虚像显示。还结合了基于极化的双通道配置，从而实现了紧凑的实现。通过光学实验验证了所提出的方案，该实验演示了60 Hz红绿蓝视频显示，每个颜色通道具有4位深度，每像素动态遮挡的最大遮挡率为90.6％。
