  • 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.
