摘　　要：Integral imaging(II)display,one of the most critical true-3D display technologies,has received increasing research recently.Significantly,an achromatic metalens array has realized a broadband metalens-array-based II(meta-II).However,the past micro-scale metalens arrays were incompatible with commercial micro-displays;furthermore,the elemental image array(EIA)rendering is always slow.The two hinders in device and algorithm prevent meta-II from being used for practical video-rate near-eye displays(NEDs).This research demonstrates a meta-II NED combining a commercial micro-display and a metalens array.The large-area nanoimprint technology fabricates the metalens array,and a novel real-time rendering algorithm is proposed to generate the EIA.The hardware and software efforts solve the bottlenecks of video-rate meta-II displays.We also build a see-through prototype based on our meta-II NED,demonstrating the feasibility of augmented reality.Our work explores the potential of video-rate meta-II displays,which we expect can be valuable for future virtual and augmented reality.
