LIU Ying, LIN Lin, ZHANG Hui-juan. Hybrid diffractive/refractive system design of head-mounted projective display using retro-reflective screen[J]. Editorial Office of Optics and Precision Engineering, 2006,14(4): 564-569
设计了有效焦距为35 mm
出瞳距离为23 mm
出瞳直径为12 mm
视场角为50的透视式头盔投影显示器。该系统由一组双高斯透镜
一个半透半反镜和一个回射屏组成。回射屏的使用使双目设计的视场有效提高
畸变明显降低;二元面的引入
使系统在尺寸和重量上有明显的减少
像质进一步提高。该系统投影镜头部分重量仅为10.8 g
最大镜头直径为23.6 mm
完全满足双目设计的要求。目视系统中需重点校正的像散和垂轴色差的最大值分别为0.12 mm和7.89 m
最大畸变<0.5 %。系统最小角分辨率为0.46 mrad
小于人眼的最小角分辨率
解决了普通透视式头盔显示器双目设计时宽视场实现难的问题。
A head-mounted projective display consisting of a pair of double-Gauss lens
a beam splitter
and a retro-reflective screen was designed
in which the feature parameters are 30 mm effective focal length
23 mm exit pupil
12 mm exit pupil size and 50 FOV (field of view). The system uses a retro-reflective screen to increase effectively the FOV of binocular design and reduce the distortion. It also aolopts a diffractive optical element (DOE)to reduce the size and weight of the system and improve the imaging quality. The total weight and the maximal diameter of projective lens are 10.8 g and 23.6 mm
the astigmatic and lateral color are 0.12 mm and 7.89 m
and the distortion is less than 0.5 %. The minimum angular resolution of this system is 0.46 mrad
which is less than that of human eyes.
