Abstract

Retinal projection display (RPD) is considered as a better solution for near-eye displays (NEDs). It can be used for the augmented-reality (AR) and virtual-reality (VR) applications. In this paper, we propose the RPD system with extended eyebox solution based on freeform holographic elements, realizing the 3×3 viewpoints array in two-dimensional directions on the pupil plane. The viewpoints spacing is 3mm, the FOV of each viewpoint is close to 40°×40°, and the eye relief is 25 mm, which can effectively overcome the eyebox limitation of the conventional RPD system. Detailed procedures of the design and analysis process of RPD system with extended eyebox will be demonstrated in this paper.
