Abstract

Space-bandwidth product in digital holography is defined as a product of spatial dimension and bandwidth of the sampled space. This limitation results in a narrow field of view or a small eye-box in holographic near-eye display. Utilizing additional micro-structured or non-periodic optics is a well-known approach that bypasses this physical constraint. However, these approaches require precise alignment and suffer from low signal-to-noise ratio in the reconstructed holographic image. In this work, we propose a novel prototype of holographic near-eye display with wide field of view achieved by axially overlapped holographic projection. The feasibility of the proposed work is evaluated with simulation and experimental results
