摘要

摘要:为标定和校准头盔瞄准具检测设备,提出一种新的光学结构,并设计了一款标准头盔显示系统(HMD)。该系统采用球面共轴设计,在有限体积的限制下满足了低畸变、高清晰的光学指标要求。利用对称性光学设计原则分步设计,设计的标准HMD系统出瞳清晰,可保证系统各种光学像差的综合校正。针对1.27 cm(1/2 in)微显示器设计了视场为30、出瞳距离为75 mm的标准HMD光学系统,各视场在分辨率30 lp/mm处的MTF值均大于0.3,系统畸变小于0.9%。设计的标准HMD光学系统形式简单、结构紧凑,光学性能优良,可作为头盔瞄准具检测设备标准件。

Abstract:To calibrate the test instrument of a Head-Mounted Display(HMD), a standard HMD optical system with a simple configuration and ascendant optical performance is proposed. In the limited space avoilable, the optical system is designed with only a spherical surface and an on-axial scheme to meet the requirements of low distortion and high resolution. By the symmetry principle of optical design, most aberrations of the standard HMD system can be corrected synthetically. The standard HMD system is used twice so that the system has a sharp exit pupil. The standard HMD system has a designed for a 0.5 inch Cathode Ray Tube (CRT) with a field of view 30? and an exit pupil distance of 75 mm. The MTF at 30 lp/mm resolution across the entire field of view is more than 0.3, and the maximum distortion is less than 0.9%. The designed standard HMD has a simple layout and compact structure, and the obtained results confirm the feasibility of the new system.
