摘要：
Systems, devices, and methods for eyebox expansion by exit pupil replication in wearable heads-up displays ("WHUDs") are described. A WHUD includes a scanning laser projector ("SLP"), a holographic combiner, and an optical splitter positioned in the optical path therebetween. The optical splitter receives light signals generated by the SLP and separates the light signals into N sub-ranges based on the point of incidence of each light signal at the optical splitter. The optical splitter redirects the light signals corresponding to respective ones of the N sub-ranges towards the holographic combiner effectively from respective ones of N spatially-separated virtual positions for the SLP. The holographic combiner converges the light signals to respective ones of N spatially-separated exit pupils at the eye of the user. In this way, multiple instances of the exit pupil are distributed over the area of the eye and the eyebox of the WHUD is expanded.
摘要（中）：
描述了可穿戴式平视显示器（“WHUD”）中出口瞳孔复制的眼框扩展的系统，设备和方法。 本发明包括扫描激光投影仪（“SLP”），全息组合器和位于它们之间的光路中的光分路器。 光分路器接收由SLP产生的光信号，并基于光分路器处的每个光信号的入射点将光信号分离成N个子范围。 光分路器将对应于N个子范围中的相应N个子范围的光信号有效地从用于SLP的N个空间上分离的虚拟位置中的相应的一个重新定向到全息组合器。 全息组合器将光信号收敛在用户眼睛处的N个空间分离的出射光瞳中的相应的一个。 以这种方式，出射光瞳的多个实例分布在眼睛的区域上，并且扩大了WHUD的眼框。
