| 摘 要： | 为了对头盔显示器的目视系统做出整体性的评价,提出了一种简单可行的头盔显示器检测方法,设计了用于检测的光学系统。根据头盔显示器与检测系统光瞳匹配的需求,在设计中采用目镜结构的成像镜头,通过一片树脂非球面镜片实现了镜头的无畸变成像。检测系统的视场角为50°,入瞳大小为4mm,畸变量<0.1%,在-4D～3D头盔目镜测试条件下都能保持很高的成像质量,可以满足不同屈光度下头盔显示器目视系统的测试需要。

| Abstract: | In order to make a comprehensive evaluation on a head mounted display(HMD),a simple and feasible testing method is proposed and an optical system for the test is specially designed.According to the requirement of pupil engagement for the HMD and the testing system,a structure of eyepiece is adopted in the optical design,and a plastic aspheric lens is used to realize the distortion-free property.The designed optical system has a field of view of 50°,a pupil size of 4 mm and a distortion less than 0.1%.It can keep high performance when the testing HMD is with diopter from-4 D to 3 D.The analyses on the design show that the evaluation system can satisfy the evaluation requirement of HMD with various diopters. |
