Abstract

Prism-based augmented reality displays are affordable solutions for head mounted devices. In this paper we supply a seldom applied reflective prism form, which does not require rays to be total internal reflected (TIR) on the surfaces. Therefore, the different folding geometry leads to more freedom in the optical architecture and better performance. Furthermore, to develop the full-color property, an off-axis element is cemented to correct the chromatic aberration. For the specifications, the eye relief is 18mm and the field of view is 50° horizontally and 30° vertically, respectively.
