Abstract

We propose a retinal projection type near-eye display with multiple viewpoints. A new optical design can expand the eyebox, a physically constrained problem in the retinal projection display. The proposed method utilizes a MEMS mirror to generate multiple viewpoints based on time multiplexing method. Since the multiple viewpoints are toward the center of the eyeball, it is possible to provide a continuous image corresponding to the eye rotation without eye tracker. We demonstrate proof-of-concept that provides expanded eyebox through the simulation.
