We demonstrate a multi-focal-plane see-through near-eye display with effective focus cues enabled by wavelength multiplexing. A spectral notch filter is implemented as the wavelength-sensitive depth separation element. The vergence-accommodation conflict can be mitigated with the proposed design without space- or time-multiplexing. Another design of a dual-focus projection module for the waveguide-type augmented reality devices using wavelength-multiplexing is also presented.
我们展示了一种通过波长复用实现有效聚焦线索的多焦平面透视近眼显示器。采用光谱陷波滤波器作为波长敏感深度分离元件。所提出的设计可以减轻聚散调节冲突，而无需空间或时间复用。还介绍了一种用于波导型增强现实设备的采用波长复用的双焦点投影模块的另一种设计。
