| 中文摘要: |
| 针对虚拟现实眼镜的光学镜片直径以及出瞳距离对视场角的敏感性做了分析,选择了最优的镜片直径和出瞳距离,采用Zemax软件设计了相应的球面和非球面镜片。对二者的弥散斑和轴外相差进行了对比,发现非球面镜片可以显著提高镜片的成像效果,并应用软件消除了由镜片导致的畸变。设计的非球面镜片视场大、畸变小,达到了预期的效果。 |
| 英文摘要: |
| The angle of view of virtual reality head-mounted display is analyzed, optimizing the diameter of the lens and the distance of exit pupil. The spherical and non-spherical lens are designed and their disc of confusion and off-axis aberration is compared by using Zemax. The conclusion is that the non-spherical lens can improve the image significantly. Distortion resulted from the lens is corrected by the software. Non-spherical lens have little distortion and large viewing angle, which can satisfy our needs. |
