Accommodative holography

Holographic displays have gained unprecedented attention as next-generation virtual and augmented reality applications with recent achievements in the realization of a high-contrast image through computer-generated holograms (CGHs). However, these show high energy concentration limited angular spectrum, whereas uniformly distributed spectrum suffer from severe speckle noise reconstructed images. In this study, we claim that two physical phenomena attributed to existing CGHs significantly limit support accommodation cues, which is known one biggest advantages holographic displays. To statement, analyze evaluate various CGH algorithms contrast gradients - change over focal diopter eye simulated based on optical configuration display system human visual perception models. We first introduce approaches improve monocular response viewing experience; computational provide images sufficient gradients. design conduct user experiments our prototype near-eye displays, validating deficient cues demonstrating feasibility proposed solutions significant improvements accommodative gains.
