Large field-of-view holographic Maxwellian display based on spherical crown diffraction

Abstract

Maxwellian display, as an effective solution to the vergence accommodation conflict in near-eye displays (NEDs), has demonstrated its unique advantages in many aspects, such as the ability to provide sharp images within a certain depth of field (DOF) without being affected by the eye’s focus. In recent years, the appearance of holographic Maxwellian displays has addressed the shortcomings of traditional Maxwellian displays, meeting the demands for flexible control parameters, aberration-free designing, and expanded eyebox. Nonetheless, the human eye’s requirement for immersion still leaves room for a significant improvement in terms of the field-of-view (FOV). In this paper, we propose a large FOV holographic Maxwellian display based on spherical crown diffraction. The proposed spherical-crown holographic Maxwellian display theoretically can cover the full FOV required by the human eyes without complex optical paths and has flexible control of performance parameters such as DOF and image quality. We have successfully demonstrated the feasibility of the spherical crown diffraction model in lensless holographic Maxwellian displays, and it is expected to have practical applications in the field of holographic Maxwellian NEDs in the future. © 2023 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement.
