Light Field Near-eye Display Resolution Enhancement Using a Staggered Microlens Array

We propose a method of improving the resolution of near-eye light field displays (LFDs) using a staggered microlens array (MLA). The staggered matrix is formed by interlacing multiple identical sparse MLAs with the same microlens periodicity. The sparse MLAs are rectilinearly shifted relative to each other such that the distance between neighboring microlenses is not one fixed value. We demonstrate that by introducing this irregular shift, the staggered MLA-based LFD can support a higher spatial display resolution.
