Research on Multi-Viewpoint Holographic Optical Elements for AR Display

In this paper, a multi-view holographic optical element (HOE) was developed for use in augmented reality (AR) displays, with a primary emphasis on its fabrication process, testing, analysis, and performance enhancement. The research outcomes demonstrate that the fabricated HOE successfully enables multi-view display, exhibiting high diffraction efficiency and superior imaging quality, thus presenting a novel solution for the further integration of AR display systems. Compared to conventional binocular stereoscopic display techniques, this approach effectively addresses the convergence-accommodation conflict, expands the eye movement range in AR glasses, and enhances user comfort.
