摘　　要：为了满足用户对虚拟现实头戴显示器大视场和高分辨率的需求,采用逆向设计方法,通过理论计算与软件仿真,设计了一种同轴大视场虚拟现实型头戴显示器的光学结构。结果表明,每个通道采用3片非球面透镜,全视场角为90°,出瞳直径为8mm,出瞳距离为13mm,在奈奎斯特频率10.58lp/mm处调制传递函数大于0.3,最大畸变为6.1%;与参考文献相比,此结构分辨率高、畸变小、像差平衡合理。该设计为优化大视场头戴显示器的光学结构提供了参考。In order to meet the needs of users for large-field of view angle and high resolution of virtual reality head-mounted displays,the initial structure of the optical system was calculated by using reverse design method,and the optical design software was used for simulation analysis optical structure of coaxial large field of view virtual reality head-mounted display.The results show that three aspheric lenses are used in each channel,and the full field angle is 90°,the exit pupil diameter is 8mm,the exit pupil distance is 13mm,the modulation transfer function is greater than 0.3 at Nyquist frequency of 10.58lp/mm,and the maximum distortion is 6.1%,respectively.Compared with the reference,the resolution is higher,the distortion is reduced and aberration balance is reasonable.The design provides a reference for optimizing the optical structure of large field of view head-mounted display.
