摘　　要：为了优化用户体验,满足虚拟现实显示器的携带方便、高成像质量的需求,使用逆向光路设计法,利用软件仿真与理论结合,设计了一种含非球面结构的VR显示系统,并进行了像质评价和公差分析。每个单目视场都有4片非球面透镜,视场角为90°,将出瞳直径为6mm,出瞳距离12.55mm,在奈奎斯特频率(14 lp/mm)处调制传递函数大于0.25最大畸变率为12.23%;文中的结构紧凑,成像质量较高,符合VR眼镜头戴显示器的设计要求。In order to optimize the user experience and meet the needs of convenient portability and high imag-ing quality of virtual reality displays,the reverse optical path design method is used,with software simulation and theory to design a virtual reality(VR)display system with aspheric structure,and image quality evaluation and toler-ance analysis are conducted.Each monocular field of view has 4 aspheric lenses with a field of view angle of 90°,a pupil diameter of 6 mm,a pupil distance of 12.55 mm,a modulation transfer function greater than 0.25 at the Ny-quist frequency(14 lp/mm),and a maximum distortion of 12.23%.The structure designed is compact,has high im-age quality,which met the design requirements of VR glasses-mounted display.
