Abstract

We propose a novel method to construct an optical see-through retinal-projection near-eye display using the Maxwellian view and a holographic method. To provide a dynamic full-color virtual image, a single phase-only spatial light modulator (SLM) was employed in conjunction with a multiplexing-encoding holographic method. Holographic virtual images can be directly projected onto the retina using an optical see-through eyepiece. The virtual image is sufficiently clear when the crystal lens can focus at different depths; the presented method can resolve convergence and accommodation conflict during the use of near-eye displays. To verify the proposed method, a proof-of-concept prototype was developed to provide vivid virtual images alongside real-world ones.
