| Summary: | Waveguides have been used as combiners for near-eye display in conventional three-dimensional (3D) display, guiding an image to each eye of the viewer by total reflection. Such near-eye displays suffer from manufacturing complexity of said exit pupil expansion (EPE), and Vergence-accommodation Conflict (VAC) inherent to the one-image-one-eye display mechanism. In this paper, a head-mounted-display augmented reality (HMD-AR) is proposed for simultaneously settling these two problems. At a time-point, lights from a display panel are transformed into a bundle of paralleling light beams, and guided to corresponding eye by a waveguide without EPE, as a collimated image. Guiding multiple such collimated images to each eye along different paths sequentially, a VAC-free Super Multi-view (SMV) near-eye display gets implemented. The proposed waveguide without EPE avoids the manufacturing complexity of EPE waveguide that requires multiple reflection planes with different coupling output coefficients. A prototype system with two geometric waveguides is set up for concept demonstration, obtaning a field of view (FOV) of <inline-formula> <tex-math notation="LaTeX">$10.2^{\circ }\times 14^{\circ }$ </tex-math></inline-formula>and a depth of field (DOF) of 1500mm. A large FOV is expected experimentally when diffractive waveguides are adopted in the further work. |
