Ergonomic‐Centric Holography: Optimizing Realism, Immersion, and Comfort for Holographic Display

Abstract

Ergonomic‐centric holography is introduced, an algorithmic framework that simultaneously optimizes for realistic incoherent defocus, unrestricted pupil movements in the eye box, and high‐order diffractions for filtering‐free holography. The proposed method outperforms prior algorithms on holographic display prototypes operating in unfiltered and pupil‐mimicking modes, offering the potential to enhance next‐generation virtual and augmented reality experiences.

Non-convex optimization for inverse problem solving in computer-generated holography

“…8b , constructs 3D volume by rendering focal stacks at different propagation depths 133 , 153 . These computationally generated focal stacks at multiple depths are jointly involved in optimization together with the target object, which enables the diffractive reconstruction to better imitate the natural defocus blur, especially in holographic display 194 . The light field method originates from holographic stereograms which reconstruct an array of directional views of the object with a single hologram 139 , 195 – 197 , as is shown in Fig.…”
