A near-eye display system (100) includes a display panel (112) to present image frames (150) to the eyes (118) of a user for viewing. The system also includes a beam steering assembly (120) facing thedisplay panel that is configurable to displace a light beam incident on the beam steering assembly, thereby laterally shifting light relative to an optical path of the light beam incident on the beamsteering assembly. The beam steering assembly may include a birefringent plate (800) configurable to replicate a light ray incident on the beam steering assembly such that the replicated light ray islaterally shifted relative to an optical path of the light ray incident on the beam steering assembly. 近眼显示系统(100)包括显示面板(112)，用于将图像帧(150)呈现给用户的眼睛(118)以用于观看。该系统还包括面向显示面板的光束转向组件(120)，该光束转向组件可被配置为使入射在光束转向组件上的光束位移，从而使光相对于入射在光束转向组件上的光束的光路横向移位。光束转向组件可包括双折射板(800)，该双折射板可被配置为复制入射在光束转向组件上的光线，使得复制的光线相对于入射在光束转向组件上的光线的光路横向移位。
