Abstract

It has always been a challenge to break the resolution/field-of-view (FOV) invariant to design a large FOV and high-resolution optical system, especially for a head-mounted display (HMD) system. In this study, a tiled HMD using two compact rotationally symmetrical eyepieces was designed and developed. Some issues on exit pupil and eye relief were analyzed in detail and taken into consideration during the design procedure. The overall optical system is compact with high performance. The system volume is smaller than 30mm×35mm×30mm. Based on two 0.61 in. microdisplay devices, the overall tiled system demonstrates an FOV of 66°(H)×32°(V) with a 7.5 mm exit pupil diameter and a 15.7 mm eye relief.
