Type: article
Abstract: Digital micromirror devices (DMDs), owing to their rapid refresh rates and ability to shape particular optical patterns, are key tools for holographic 3D near-eye displays. However, relying on a single-sideband (SSB) filter to eliminate crosstalk from zero-order and conjugate noise leads to an enormous decrease in the utilization of spatial bandwidth product (SBP). In this paper, we develop a new strategy for the binary hologram optimization framework to enable the full utilization of SBP of DMD holographic display by minimizing conjugate noise. Meanwhile, we design a binary operator to estimate the binarization process during the hologram optimization procedure. The experimental results demonstrate our approach can achieve higher SBP and competitive reconstruction quality compared with the conventional single-sideband filtering method.
